wait, can u work out the formula to do that? im kinda brain dead =/
y = 24 * [ sqrt(5) * sqrt( d_f + 20 ) - 10 ]
i think this is what we had for duration...
let me find your original msg
Aluminum
Aug 28, 2021 3:15 AM
if decay remains the same, just substitute the "total decayed guage" for d_f
(edited)
i.e. add whatever the top-up adds to the freeze guage and that will give you the total time
srl
Aug 28, 2021 3:16 AM
so calculate total gauge decayed between first freeze and 2nd freeze, then add the 2nd freeze gauge to it?

Aug 28, 2021 3:17 AM
d_f(t) = -1.25 * t^2 - 10 * t + d_f(0), where t is in seconds
correct?
(edited)
er i guess i can't write d_f(0)
there
Aluminum
Aug 28, 2021 3:18 AM
I think that was the formula yeah
srl
Aug 28, 2021 3:18 AM
ok so changing that to frames i get
d_f(t) = -1.25 * (t/60) ^ 2 - 10 * (t/60) + d_f_initial
Aluminum
Aug 28, 2021 3:19 AM
srl
Aug 28, 2021 3:22 AM
ok so rearranging that and solving for t where 0 = -1.25 * (t/60) ^ 2 - 10 * (t/60) + d_f_initial
(edited)
so we want the positive root here, so we have t = 24 * (sqrt(5) * sqrt(d_f_initial + 20) - 10 )

trying to get one where im refreezing with barely any cryo left but it's hard

i think the question we're trying to answer is does freeze, unfreeze, refreeze result in a shorter duration right?
my hypothesis would be that it doesnt. it's purely dependent on how much freeze gauge there is

┌─── reply to message (881027552368549918)
Isu
Aug 28, 2021 4:11 AM
my hypothesis before was that the decay rate gradually scales back down to the base of 10 units per second, at the same rate at which it increases. Which matched the first test I did back then, but then I dropped it and only did the one test so not enough samples to say that with any certainty
srl
Aug 28, 2021 4:12 AM
so a quadratic decay back down to 0?
(edited)
Aluminum
Aug 28, 2021 4:13 AM
Isu's speaking from a velocity perspective
(edited)
the rate of change goes back to 10
srl
Aug 28, 2021 4:13 AM
so im understanding it as, decay maintains the last frozen's rate at the end of the freeze, but falls to zero as time passes
Isu
Aug 28, 2021 4:14 AM
so my hypothesis would be that while frozen, decay increases by 2.5 units per frame, and while unfrozen, decay decreases by 2.5 units per frame until it's back to the baseline
srl
Aug 28, 2021 4:14 AM
we really standardized need units.. this is hard to discuss
(edited)
Isu
Aug 28, 2021 4:14 AM
2.5 units per second, so 2.5/60 per frame
srl
Aug 28, 2021 4:14 AM
i think we're saying the same thing, maybe
srl
Aug 28, 2021 4:15 AM
really wonk if they did that hmm
trying to think if there's an easy way to test that on minecraft server where it's possible via reaction to see the actual gauge values
Aluminum
Aug 28, 2021 4:17 AM
A simple symmetry test for Isu's hypothesis: Any refreezes after the first freeze runs out within the same duration as the first freeze will have a reduced duration under Isu's hypothesis.
This can be checked in game (easily?)
(edited)
srl
Aug 28, 2021 4:17 AM
try 2 would be exactly that
i can test it water i think
cause the conditions are just that i trigger 2 freeze w the exact same freeze gauge i.e. 25
like unfreeze, wait 30 frames, freeze again

like how would u scale the decay rate down?
dont u have to change the durability formula from a continous function to a discrete one...? or i guess not
wait.. do u just subtract the same function for the time passed in between?
srl
Aug 28, 2021 4:47 AM
I guess the 1st derivative is just a linear line. So you would have a line w slope -2.5 for t=0 to t=first unfreeze, then another line w slope 2.5 for t= first unfreeze to t=second freeze. Then back to slope -2.5

Then.. take the integral of that function and uh…

yeah i looked over the 3 tests i did and it's the same for them
does it line up if you double the decay recovery amount? it lined up almost perfectly with two of my tests but not with the third so might just be a coincidence (by almost perfectly i mean the calculated second freeze duration was at most 1 frame off)

closer but cant tell if coincident or not
need a much larger sample size w diff freeze duration i guess to see if it's just a coincidence or not
the differences are also weird, they're not consistently in one direction
sort it by time in between freeze, the last 3 are basically back at their original duration
actually let me try 2U freeze maybe that'll show something. wondering if it's just something simple like if refreeze within 2s, subject to some sort of duration decay
otherwise it's back to normal
Isu
Aug 28, 2021 2:56 PM
well, under that hypothesis, for the last 3 the decay rate would have been back at the baseline since the time between freezes was more than half of the first freeze duration
but yeah i don't have a lot of confidence in that hypothesis so far with some of these differences... but then it's also weird to me that you get such large variations for a simple 50 dura freeze anyway
srl
Aug 28, 2021 2:59 PM
ya... hoping for it to be a simple explanation
has anyone every tried something like
50 electro, wait for expire, reapply 25 units within 10 frames, and see if the decay rate of the 2nd application gets applied?

you multiply it by durability to get the duration in seconds, or rather what the duration would be if the decay rate remained constant. Same thing for regular auras, they have a duration constant of 0.1, so e.g. a 1u application becomes 25 * .1 + 7 = 9.5 second duration
at least that's how i interpret it?

One solution is to just collect a ton of data and have solver try adjusting each of those variables
And see which one fits best
And then work backwards and see if the solution makes sense
Kourinn
Aug 28, 2021 4:42 PM
okay so using basic d = a*t^2 + v*t
the frozen gauge consumed while frozen is c = 1.25 * t^2 + 10 * t
so extending a freeze at 3 seconds by 100 frozen gauge, c(3s) + 100 = 1.25 * t^2 + 10 * t
so 1.25 * t^2 + 10 * t - 141.25
and t = 7.358
from quadratic formula
so extension = (-10 + sqrt( 100 - 4 * 1.25 * ( d_f + c(t_f) ) )) / (2 * 1.25) - t_f

"Ability_Freeze_Duration": 0.20000000298023224,
my gut feeling is that this variable gets adjusted somehow after each freeze/unfreeze
-1.25t^2 - (2x/(x*.2)) * t + 2*x
let t be time in seconds
let x be the amount of cryo/hydro reacted in units
let r be the duration rate of freeze
let d(t) be the durability of the freeze at time t
then:
d(t) = -1.25t^2 - 2t/r + 2x

solving for t when d(t) = 0 gives us

so instead of v = 10 + 2.5 * t

You'd never wrap around the peak because you start beyond it...

you can tell you start beyond the peak since v = 10 +2.5*t
is strictly increasing...
it might be worth testing exponential formulae. Make sure it works with freeze without extension too...

Should actually be able to tell if it's quadratic or exponential by comparing across very long vs very short freezes (and some values in between)

okay yeah v = 10 + 2.5 * t

Permafreezing a Lawachurl for 9.85s then triggering a 39.6 d_f freeze lasts ~1.18s. Exponential predicts less than half a second, so that's wrong.

Once we have enough data points, we can connect the dots on the starting velocity and try to figure things out from there (like whether or not that even works or if there's adjustments to the acceleration somehow)

= Freeze Extensions =
[Requirements]
- Ability to record
- A love for all things cold (and boring)
[Details]
Currently, we know that if a target is frozen, unfrozen, and subsquently frozen again, the duration of the 2nd freeze is somehow reduced. The reduction appears to relate to the time in between the first and 2nd freeze. However, we do not have the exactly formula for the 2nd freeze factoring in this reduction. Therefore, we need a large sample of data in order to try and work backwards what the formula may be. The purpose of this theory hunt is to collect said data.
You will need to record videos of freezing a target twice. Each video should be as follows:
- Against a ruin guard standing in water (there should be one east of the teleporter in Yaoguang Shoal)
- Initiate first freeze
- Wait for first freeze to fall off (use elemental sight to confirm)
- Initiate second freeze
- Observe with elemental sight when second freeze falls off
Make sure that it is not raining when you do this
For each recording, try to vary the time between when the first first falls off and when the second freeze is applied. The gauge of the freeze applied should be some combination of the following:
1U initial, 1U second
1U initial, 2U second
2U initial, 1U second
2U initial, 2U second
We will need lots of sample size for each of these (10+ at least).

Isu
Sep 4, 2021 1:31 PM
remember that the ruin guard isn't actually in the water while he's on top of the ice. so in this case, E triggered the second freeze, the dash applied a new cryo aura, and then once the ice beneath him expired, the water triggered freeze
i think it makes more sense to start with tests where we take advantage of the rocks in that area to gain enough height to avoid freezing the water

i'd like to also get input from @Aluminum
So the original purpose of this ticket was to understand the decay rate/duration of freezes when consecutive overlapping freezes are applied. In the case of there being no gap between the freezes, it seemed like you guys arrived at the (probable) answer, is that correct? If so, do you think we could at least collect footage for this and verify it (since IIRC the evidence before was from an inadmissible source)?
Then we got distracted by trying to figure out how it works when there is a gap between freezes, which I believe is still undetermined? Perhaps we can get the first part out of the way and leave this as a matter for another ticket if we haven't figured it out

(edited)
Aluminum
Sep 24, 2021 2:52 AM
isn't the difference between 2 quadratic formulae... one quadratic formula?
could it be reasonable understood as a "deceleration" of the decay velocity between the two freeze applications?
Since freeze extension with overlap is understood as a "continuation" of the decay velocity.
Well nevertheless I look forward to your results. The general formula for freeze durations would be one of the big mysteries solved!

Oh btw I think your current formula is equivalent to this one^
(edited)
So rewording in terms of velocity/first derivative
Freeze decay starts off at a rate of 10/s and accelerates at a rate of 2.5/s^2
When unfrozen, it then accelerates at a rate of -5/s^2 back down to a minimum velocity of 10/s
(edited)
@Kourinn I've validated this to be equivalent to your formula, do you agree? ^
I'll be taking a look at your clips tomorrow

@Aluminum Yeah should be the same. Both formula are derived from decay d=1.25t^2+10t
with recovery r=2d
. Kinematic formula is x=(1/2)*at^2+vt+x0
so a=2.5 and v=10.

Sep 25, 2021 4:32 PM
My guess is that the formula is correct, but Unity event queue timing and simplistic event handlers is the culprit.
I doubt there's a fixed recovery delay because, revisiting my long permafreeze tests, with no unfrozen gaps, the formula predicts shorter than observed frozen duration, with larger difference for longer durations. Based on datamined config variable naming (like "thinkInterval" and "onThinkInterval") I believe most mechanics use a simple interval, and if the event queue has a lot of items or unfortunate timing, the function might be delayed.
If the function is written in a simple way (like "add x to y", trusting the interval timing and not multiplying by delta time) then small delays can add up over time for noticeable effect. This would also explain why similar frozen-unfrozen durations can both over and under shoot expectations.
Kourinn

I used a macro to try to replicate the same scenario multiple times, to test frozen duration consistency.
Results were inconsistent for very similar situations, sometimes producing both positive and negative error.
Thus finding a more accurate formula does not seem likely, and I am in favor of closing this ticket for review/publishing.

@Aluminum looking good. y axis is difference in freeze duration between 1st and 2nd, x is frames between 1st expiring and 2nd freeze. at least it doesnt look random

so color change is usually 1 frame after frozen pops up
linear correlation between time elapsed and freeze duration diff.. does that tie into the formula you guys have?

freeze duration is weird even without the refreeze tax.
i did a few tests for example 50 freeze lasted for 210 frames, but 100 freeze - 25pyro also lasted for 210 frames, which is weird and i cant make sense out of the decay rates anymore
(edited)
Isu
Nov 3, 2021 7:39 PM
isn't that just the expected result? forward melt so 2x the pyro trigger is removed, so that leaves 50 durability to decay over time, which your previous test showed to be 210 frames
phaZZi
Nov 3, 2021 7:44 PM
well it would only work if freeze decays at the same constant rate for all initial freeze durabilites triggered from reactions.
so if a 50 freeze lasts 210 frames, a 100 freeze (without interference) should last 420 frames - which it doesnt, it lasts around 340 frames. so it decays at a faster rate. if i reduce it down to 50 durability, then with a faster decay rate it should end earlier than 210 frames, which it also doesnt either

"Freeze decay starts off at a rate of 10/s and accelerates at a rate of 2.5/s^2"

like it's just off a little
not to mention my gut feeling is that the system works on some sort of tick system so sometimes results are inherently off a little

and hopefully it avgs out close enough to 2x decay rate... this way can just say 2x decay rate since it's easier to remember than 1.9234729342 (i made this up)

if you sucrose swirl both hydro and cryo from two enemies onto a 3rd enemy you should get consistent 88 durability freezes, probably also no hitlag. is that useful for testing?

oh. Ah I see. The formula has a -1.25t^2 component. But velocity is the derivative of that. That's why acceleration is -2.5/s^2 instead of -1.25/s^2 btw

Nov 4, 2021 3:41 PM
velocity is literally just v(t) = v0 + a*t tho. acceleration is the derivative of velocity not the other way around. you could also see that v(t) is just the basic form of the integral of acceleration
am i turning full pepega again
ah nvm youre right, for the "reverse derivative" for distance (or durability d(t) here) youd get d(t) = d0 + (v+v0) * t + 1/2 a * t² , where 1/2a = -1.25

Is it possible to extend freeze while an enemy is already frozen (w/o shattering them first)?
Asking bc in this video (first clip) I hit the slimes once (to freeze them), then a second time (which I don't think changed the time, since I got around the expected duration when timestamping for the left and middle slime) and then I hit the right slime again and that one was frozen for quite a while longer than the other ones https://www.youtube.com/watch?v=QCTUM34BzjA&ab_channel=ElliElliElli

mmh thinking about it a bit made me realize that there are multiple parameters that could be adjusted.
the "unfreeze" part of that formula could be ignored for now by doing perma freeze tests first.
was there already an established freeze duration formula before this ticket was opened or was it found out during this ticket and would it also need any further evidence? otherwise it just make it more complicated to figure out everything at once from what understand.
i just guessed t_decay = t_frozen - 1.9 t_unfrozen

freeze duration formula is from before this ticket, Aluminum and srl primarily figured out the formula and then there was a theory hunt to gather more evidence for it. I personally don't think more evidence is required for the general freeze duration formula at this point, and there is a formula for it in the TCL now although it may be updated with the EGT rewrite: https://library.keqingmains.com/mechanics/combat/elemental-reactions/transformative-reactions#frozen

Nov 13, 2021 11:58 PM
In my opinion, it's not possible to find a truly accurate formula. There is jitter in both directions to the degree of estimates being off by 10% in either direction. I told aluminum I was in favor of closing the ticket with the current understanding (see pins) with the disclaimer that there's some random factor at play.
Iirc, Srl wanted to collect tons of data to try to statistically assess the noise, but nobody has time for that.
ElliMiku
Nov 14, 2021 10:19 AM
It doesn't need to be noise free to find an accurate formula. You just need, yes, enough data and more advanced techniques to analyze the data.
For the 10%, that's quite a lot, but still manageable imo
For the "randomness", is it possible it's not truly random but we're just missing a variable?

maybe there is a maximum freeze decay rate just a random thought that i just had
ElliMiku
Nov 16, 2021 11:19 PM
I feel like I am overengineering this
I tried making a nice data analysis, using function fitting tools from scientific python, but the results aren't rlly telling me enough. It both doesn't clearly prove the hypothesis, nor clearly show it's incorrect. Also I have trouble plotting the optimized results nicely bc i have optimized for two variables.
(edited)
Here's the plot with the kourinn formula from the pins
What I currently don't take into account is the aura decaying before the enemy is frozen - hence the "2B" data being so far below the "2B" line - in fact the freeze aura was at around 36 for both the 2B and 1A tests most of the time. Will implement tmr and see if it radically changes stuff
(edited)
Another note, my data is "filtered" by cumulative time unfrozen < 2.5, simply bc I did take quite long strings of freezing and refreezing again within less than 2 sec and it was kinda all over the place for higher numbers of refreezing
open questions:
- is t_decay a "good" variable
- functional shape of the decay
- does it work differently with innate hydro aura enemies/enemies standing in the water
- how does it work for long strings of freezing and unfreezing
suggested course of action:
- use data to find an "initial freeze decay" rate for the first refreeze happening shortly after unfreezing
- use this rate to make a makro that refreezes quickly after unfreezing for the first few times, record data
- use data to find approximate formula in terms of total freeze time (so we can ignore the effect of unfreeze time)
- if successful, use above formula + more makros to test for effect of unfreeze time

@phaZZi made a mistake in his calcs, you subtract unfreeze from the previous freeze, not the current freeze which you're calculating. After correcting his numbers, 1.9 does seem like a more accurate coeffient for his data, but none of his unfrozen durations were very short. The coefficient may vary with unfrozen duration, something like 2*unfrz/(1+0.1*sqrt(unfrz))
. That or Ganyu's arrows have enough enemy hitlag to skew my tests toward higher coefficient.

Current formula was mostly the work of srl, aluminum, and Isu. Prior to this ticket, I had a ticket named #freeze-extension
that found consecutive freezes (without unfrozen gaps) showed reduced duration roughly matching 1-0.25*ln(t_frzn)
. After learning a bit more about freeze (and swirl) from them, I documented the current formula from my tests (which also matched one of their guessed formula). Since this formula works both consecutive freezes and with unfrozen gaps, my previous ticket was archived.
Which reminds me, I should transfer my ayaka hitlag extension tests to the doc here. The finding is that hitlag pauses both freeze decay and decay acceleration. There's a chance this means hitlag might pause unfrozen decay recovery too.

i guess with the slight adjustment the formula does work pretty well for my test, except for the first freeze which annoys me a little. it would fit better for the 1st freeze if i adjust the hydro slime gauge to 48 instead of 50 lol (in that case consecutive freezes would then fit better with 1.93 as unfrozen coefficient)

we also cant fully accurately control the tests though
i have noticed in the logs that sometimes the hydro doesnt fully refill for w/e odd reason before refreeze
like it's just off a little
not to mention my gut feeling is that the system works on some sort of tick system so sometimes results are inherently off a little
i.e. it waits for next tick type of thing
all of that together makes it kinda hard... so that's why i think should get more sample
and hopefully it avgs out close enough to 2x decay rate... this way can just say 2x decay rate since it's easier to remember than 1.9234729342 (i made this up)

that's the assumption im operating under. i mean i could be wrong but this kinda of frame inaccuracy is also present in devkit where you can see in the log that the gauge consumption is identical but the frames are off a bit
so that's why personally im ok making that assumption
and then from there, i'm just working backwards where if the 2nd freeze lasted say.. 150 frames, well what does the starting decay rate have to be?
and let's say the starting decay rate is x, then does that fit the model that it recovered y/s starting from first unfreeze to second freeze

I still think it's worthwhile to try it my way and see if the two approaches reach the same answer
If I'm feeling fancy I can try assuming some specific uncertainty on the data (so assuming the measured time doesn't match the actual time) for the fitting algorithms to process

compare this to:

ElliMiku
Nov 23, 2021 10:28 PM
t_decay is just an intermediate variable, really
it is based on total (up to this point) frozen and unfrozen time
similar to the formula in the pins
the idea is that while the enemy is frozen, the freeze time of the next freeze is decreased
the longer it's frozen, the more it decreases the time for the next freeze
after the first freeze it may be unfrozen for a while
during the time unfrozen, the freeze time (again for the next freeze) "recovers"
and it recovers 1.9 - ish times (when unfrozen) as fast as it decreases (when frozen)

what is b and c if you rearrange that back into the pq formula tho
(edited)
the pinned formula is actually the pq formula but rearranged from:
sqrt( 400 + 20*d_froz + 25*t_decay² + 200*t_decay )/5 - t_decay - 4
<=>
sqrt((400 + 20*d_froz + 25*t_decay² + 200*t_decay)/25) - t_decay - 4
<=>
sqrt( 0.8*d_froz + t_decay² + 8*t_decay + 16 ) - t_decay - 4
<=>
sqrt( 0.8*d_froz + (t_decay + 4)² ) - (t_decay + 4)
with (t_decay + 4) = p/2 and 0.8*d_froz = -q

Nov 23, 2021 11:59 PM
so -2.5 is the t_decay coefficient used in that rearranged pq formula which makes sense, since from the vanilla tests, we assumed the decay_acceleration to be -2.5 (so every extra second will add -2.5 to the initial decay_velocity). now with your coefficients that would probably affect the initial decay_velocity w2 as well as the decay_acceleration w1 of it, so we would get... 
EDIT: idk i cant make sense of the pq formula anymore if i use your b=24.5, c=270 as coefficients, i end up with
sqrt(
(16/0.98-5.4²=-12.83347) + 0.8*d_froz
+ (t_decay + 5.4)²
)
- (t_decay + 5.4)
+ 1.4
with p/2 = (t_decay + 5.4)
-q = -12.83347 + 0.8*d_froz
but now there is also this random +1.4 floating around which doesnt belong anywhere in the pq formula. i think the way you parameterized the formula doesnt really make sense. it should probably be in terms of p, q or w1, w2, w3.
given the vanilla freeze tests, the current assumption is a quadratic formula with
1/2 decay_acceleration:
w1 = -1.25
initial_durability:
w3 = d_froz
initial_decay_velocity:
w2(t_unfroz=0) = 2 * w1 * t_decay(t_unfroz=0) - 10
= 2 * w1 * t_froz - b * t_unfroz=0 - 10
= 0 - 10
= -10
it would also make sense to assume different parameter b or a different function for t_decay or maybe t_unfroz isnt even a parameter inside t_decay but appears somewhere else in the entire formula.
other ideas that i had were that maybe t_decay has a max_value or the game only cumulates t_decay over the past x frames instead of all frames since the first freeze

Nov 24, 2021 8:31 PM
I can try with a different parametrisation. If I'm not mistaken, the only thing we're reasonably sure of is the initial freeze duration,
d(t_frozen_total=0, t_unfrozen_total=0) = q = w3 / w1
so that still leaves parameters for
d_decay = d_frozen_total - a * d_unfrozen_total
and
p/2 = t_decay + v
(so only 2 unknown params, a and v (which means that I have been "overfitting" indeed))
That's ofc assuming that d_decay is a "reasonable" variable.
For other formula, I also tried the known value as a starting point
d(t_frozen_total=0, t_unfrozen_total=0) = q
and then exponential decay in terms of d_decay
d(t_decay) = q * exp(-c * t_decay) = q * exp(-c * t_frozen_total) * exp (-a * c * t_unfrozen_total)
(which ofc gave me a diff value for a).
I also plan on doing just linear fits,
d(t_frozen_total, t_unfrozen_total) = q + w * t_frozen_total, r * t_unfrozen_total
(which I don't expect to give good results, but would be a nice "control" case imo)

it would also make sense to assume different parameter b or a different function for t_decay or maybe t_unfroz isnt even a parameter inside t_decay but appears somewhere else in the entire formula.
This is ofc possible, but all "reasonable" shapes of a function of t_frozen_total and t_unfrozen_total I could come up with are the ones I mentioned above. Except maybe a formula quadratic (or rather squareroot-ic) in both t_\frozen_total and t_unfrozen_total independently? If you have any other guesses lmk and I see if I can include them.
other ideas that i had were that maybe t_decay has a max_value or the game only cumulates t_decay over the past x frames instead of all frames since the first freeze
Max value should be kinda straighforwards to check, the other is ofc also possible to check, but will require some more thought and time from me.

I didn't take into account that the initial freeze time is well known and I should have, so there's only two unknown parameters for the "sqrt formula" (rather than 3). Hence the unaccounted for -1.4 that phaZ noticed.
Also there is other stuff to check in principle, like different functions in terms of t_frozen_total and t_unfrozen_total (or possibly other variables), but idrk how these would look like, or if there's a max value for t_decay, or if d_decay is only counted only for the past x seconds (the latter would be a bit of a headache ngl)
Hope that explains it a bit better!

that would explain why the formula didnt match for the first freeze in my test. would also mean freeze duration wouldnt behave quadratic once the cap is hit. but freeze durations would be way too long with that -20 decay_velocity cap in my sheet currently, and rn i still have the quadratic formula in there even at the cap. but could still be slime durability being guessed wrong so ill try guess some freeze durabilties lets see... nvm then

This still doesn't account for the large error when refrozen many times. My best guess is something to do with "AttachAbilityStateResistance" or "WatcherSystemMixin" being delayed by calulation complexity or competing threads.

like i mentioned the hydro not always refilling consistently. in addition the original freeze duration isn't totally consistent
i think a part of it too is b/c the game doesn't operate on a per frame basis. there's probably some sort of internal ticking system (maybe even on a per target basis) that doesn't line up perfectly with frame updates
it's just too many external factors that at this point i'm willing to settle on a "close enough", and only b/c that "close enough" appears to be backed by some sort of datamine
semantics but for me personally if we didnt have any datamine backing it up, i'd say the formula we found is a best case simplificatin/approximation.
since we do have datamine backing it up, i'm ok claiming the formula is the correct one, subject to in game frame inaccuracies

well first of all you're chain freezing with no elemental sight to use as a control point on when the actual freeze/unfreeze occurs (eyeballing it will easily introduce +/- 5 frame inaccuracies)

it's simply not a very controlled test so it's not surprising that results have such huge variance

also keep in mind that if u chain freeze like that instead of starting with a base case of 2 consecutive freeze, if every freeze has +/- a couple frames error, by chaining so many of them you're just compounding the error
that's why all of our previous test is just 2 freeze next to each other, not chained

freeze text frame = frame cryo aura shows up in elemental vision, 1 frame before cryo is under boss bar. frame of freeze aura disappearing over enemy = frame of freeze aura disappearing under boss bar = frame of cryo aura disappearing in elemental vision. thats about what ive written about my frame counting method in the sheet as well
about the water not applying enough hydro aura, i dont think its the case but i also want be on the safe side and i have changed the time like 10 minutes straight fishing for rain and it didnt happen, mb ill do it later haha

actually that error doesnt even compound because the calculated freeze duration is not based off of the previous calced freeze duration but on the measured f_frozen/unfrozen triggers and the measurings are independent of each other, so are the measuring errors.
purge_rate error of course is compounding in the way aluminum mentioned and cant be measured but added as a constant error term or error function to each un/frozen duration. but some simple error guesses did not do the trick for me https://discord.com/channels/763583452762734592/881008110699937792/914315236339769354

ure right. t_decay is proportional to the sum of each measured freeze duration, and the expected value of the errors sums up, thats basically the purge_rate error yea. idk what i event meant with the first thing, proof that its too late for me again. till tomorrow

@Aluminum btw just had a thought. you know how yesterday we were looking at first differences and if we start at 10/60 as velocity the very first first difference is only half of what was expected?
i wonder if that accounts for some of the observed differences vs the formula? possibly that the game implements it the same way. i.e. start at 10/60 and just subtract the constant instead of starting at 10/60 - 2.5/3600
i.e. the whole discrete vs continous thing

I was trying to say that to you earlier. Even so there's only about half a frame of difference between the two
In terms of formula it just replaces the t^2 component with t(t-1) or t(t+1) depending on whether you increment the decay before or after subtracting it from the gauge

ElliMiku
Nov 29, 2021 5:05 PM
oh I think that's due to
1) some are 1A with aura tax and some are 1A without aura tax (e.g. in the rain)
2) the condition for freeze decay to reset is dependent on the frame counts, which are not 100% accurate, so sometimes the calcs come out as it resetted, so now it's the first freeze again when it actually wasn't by a small margin
phaZZi
Nov 29, 2021 5:19 PM
was actually wondering. how do you fit a single curve when its a function with frozen_durability as parameter? like in the swirl test, the frozen durability is higher and the points are clearly nowhere near the estimated function

Nov 29, 2021 6:18 PM
alright, ive done 4 longer aloy vs ruin guard tests (with water and with rain)
im not done with frame counting even the first one but here is a diagram for now:
for the red dots, i took the data mined formula, but changed my f_trigger_frozen to be 2 frames earlier than what ive measured (or f_unfrozen 2 frames later). so that way the "observed" frozen_duration is increased by 2 frames every time and the unfrozen_duration decreased by 2 frames.
then its fairly close to the blue actual freeze duration
https://puu.sh/Ispka/e90c855251.png
(edited)
btw when shooting on aloy, elemental sight does indeed show f_trigger_frozen 1 frame later than the freeze text (which is the opposite of the adjustment that ive made looool). i guess thats hitlag related. i have still counted frames according to when the freeze text showed up, tho

either increasing frozen_duration by 2.5f / decreasing unfrozen_duration by 2.5f or unfrozen_coefficient=1.85 both give the good results for this test and also work for my swirl freeze test.
for the first aloy test i did, only unfrozen_coefficient=1.85 would go well but not the other, but that test wasnt done under ideal circumstances i guess

https://github.com/ellimiku/freeze_extension_analysis
Latest program output as a txt attached (as a temporary solution till I transcribe it into the doc)
My conclusion: With parameters
a = -1.86 ± 0.02 , b = 4.04 ± 0.02
(compare to datamined values: a = -2, b = 4
) It is fair to say that the square root formula is correct. The deviation form the datamined values may be due to discretization effects. Which value to use in practice depends on the situation, but it probably doesn't matter that much.
Without background knowledge the exponential function and the square root function are equally good matches, but the linear is unsurprisingly worse than both.
Best params for exp function: a = -1.71 ± 0.04 , b = 0.113 ± 0.003
Best params for linear function: s1 = -0.34 ± 0.01 , s2 = 0.53 ± 0.02
(has largest relative std. error)

so a couple minor points. i think you should clearly state the units for both time and durability somewhere. i.e. is this using the 1/2/4 unit scale? or is it 25/50/100 unit scale? and is time in seconds? or frames
the formula themselves looks a bit unfamiliar to me i think b/c of the units (i kinda just never looked at the 1/2/4 version of the equation tbh, sorry 😦 )
imo, the advance egt will most like use time in seconds and durability in 25/50/100 scale so i wonder if it'd be best to have this in those units as well. that's however a question for the editors and not me

maybe mention that the pq formula is derived from
durability_frozen(t) =
durability_frozen0
+ (decay_velocity0 + decay_velocityBase) * t
+ 1/2 * decay_acceleration * t²
where
decay_velocity0 =
min(0, decay_acceleration * t_decay),
durability_frozen0 =
2 * min(durability_hydro, durability_cryo),
t_decay =
sum(
max(0, t_frozen_i - a * t_unfrozen_i)
) over all previous frozen and unfrozen instances i
and we were looking for a in above formula
and b would be = decay_velocityBase / decay_acceleration
in a previous ticket decay_velocityBase has been determined to be -10
and decay_acceleration to be -2.5
idk if thats nessecary but maybe itd help to understand what has been done in the calcs

stupid formula suggestion for the t_frozen equation part with gauge units:
sqrt(
20 d_frozen + 25 (t_decay + b)²
) / 5
=
sqrt(
(20 d_frozen + 25 (t_decay + b)²) * 1.25
) / 5 / 1.25²
=
sqrt(
25 d_frozen + 31.25 (t_decay + b)²
) / 7.8125
=
sqrt(GU_frozen + 31.25 (t_decay + b)²)
/ 7.8125
in the end itd be
sqrt(GU_frozen + 31.25 (t_decay + b)²) / 7.8125 - t_decay - b
idk if that looks nicer, obivously you could also just replace 20 d_frozen with 0.8 GU_frozen

Ok yep I need to look at my write-up doc and change some things (bc I assumed that freeze decay resets after 2 sec unfrozen, idr why)

ElliMiku
Dec 15, 2021 5:00 PM
Finding: The duration of repeated freezes can be described by the following formulae:
t_decay =
sum(
max(0, t_frozen_i - a * t_unfrozen_i)
) over all previous frozen and unfrozen instances i
t_frozen_(i+1) =
sqrt(20 * d_frozen + 25 * ( t_decay + b)²)
/ 5 - t_decay - b
The variable t_decay is just needed for the calculations. If t_decay would be negative it “reset†to zero.
The freeze duration in seconds is equal to the second formula. The value d_frozen is in elemental durability and is equal to twice the minimum of the cryo or hydro gauge when freeze is triggered.
This is derived form the "kinematic approach":
durability_frozen(t) =
durability_frozen0
+ (decay_velocity0 + decay_velocityBase) * t
+ 1/2 * decay_acceleration * t²
where
decay_velocity0 =
min(0, decay_acceleration * t_decay),
durability_frozen0 =
2 * min(durability_hydro, durability_cryo),
t_decay like before
And then solving for t (generic solution to quadratic equation). This was done in a previous ticket. https://tickettool.xyz/direct?url=https://cdn.discordapp.com/attachments/866091819946344458/901006429228498964/transcript-freeze-extension.html
For the frozen durability in GU the formula is:
t_frozen = sqrt(GU_frozen + 31.25 (t_decay + b)²)
/ 7.8125
The parameters I found are a = -1.87 ± 0.01 and b = 4.09 ± 0.02, while the datamined values are a = - 2 and b = 4. Data analysis form various people are consistent with b = 4 and a being between 1.8 and 2.0

So the basic gist of it is that unlike normal gauges, which do a duration calculation to set the initial decay that stays the same, Freeze starts off at the same decay rate regardless of initial gauge.
Then it has some acceleration stuff that can be seen in the pin.
Solving for duration gets you the equation with the square root. And then we fiddle with the two unknowns, (a) which relates to the recovery acceleration in terms of the decay acceleration and (b) which relates to the starting decay, to come up with as best a formula for freeze duration as possible.

It's already added to the advanced guide by srl, the advanced guide is not in the TCL though.
I'd say to include both the formula described as simply as possible as well as a "kinematic description" with words that I pinned. The TCL is using U instead of durability though so there's a bit of translation to be done.
