Dexterity's impact on critical hits

[Cream Soda]

With the gear in my avatar, swap out merman's for minuet, I do 85% on lv 82 birds, higher on lv 81 birds. Throw in focus and I'll usually parse 88-92% at a colibri pt as mnk.

[Shinryuu]

Well you're going to have more accuracy than me; I gain ACC on neck (PCC) and my DEX (80), while you have 7 more on head, 7 more on feet, 2 more on ammo, 1 more on body, presumably 4 more on rings... I need to finally get the 25 piece for usukane somen, I've had the 35 piece for a bit. I use noritsune kote, by the way. Attack hands are overrated.

I don't remember parsing as low as ~80% or less without ACC songs on birds, though. Do you have 8 H2H? As I've said before I'll go merit on MNK sometime soon again. I became too infatuated with WAR.

[Cream Soda]

Yes, I have 8/8 h2h and while focus is up, I swap to turban and Bkote. If by some reason we have madrigal for other DDs, I'll use rajas as well. And yes, x2 toreador's.

Don't know if you're still interested in more data but I just did two sets of 500 swings on Greater Colibri which according to wiki has 67 AGI. This puts me at 53 more DEX than the Colibri.

This was on SAM, which is the reason it's a small sample.

Other mods:
Crit merits +4%
Claymore grip +3%

First sample:
19.60% critrate

Second sample:
18.28% critrate

I know from earlier tests (sadly all gone now with numerous disk formats) that adding more DEX (not much) will put me around 25-28%. The addition of certain items I've found it hard to live without have forced me away from the max DEX-setup, but recently we've seen items added that I could use to boost DEX again, like Cuchulain's mantle and Hachiryu kote. Just need to grind a bit to attain them.

[Loziel]

Could people perhaps do these tests without the use of critical weapons and grips so we can get a cleaner set of data. unji and senj are not good to test this with based on how each hands crit is independant of the other weapon

[Agana]

I'd like to see some dex testing on drakesbane, vs. str testing :3

[urat]

Did some quick stat plot / regressions, if the difference between your dex and mobs agi is only variables that influence crit rate (not including crit rate armor/weapons cause those are added in after)

Then the exponential regression appears to be:

Crit rate= o.339 x 1.077 ^ (your dex-enemy agi capping at 0)

then add in gear.

I'll take a look at other forms of regression to see if any other forms fit better, but this one is almost dead on.

[Masamune]

Sorry for necrobumping, but i'm wondering a few points:

1. How did you guys differentiate your Crits numbers from Normal ones since that update which changed all pDIFs ? asking that because my recent tests (posted here @ BG) on pDIFs under capped conditions showed dmg numbers totally wrong with pDIFs listed @ wiki (at the exception of 3.15 cap which most poeple figured), resulting maybe in wrong differentation between Normal Highs and Lowest Crits, in tests involving crits or pDIFs?

2. Does any -rigorous-test exist regarding crit% @ 100/200/300TP for RagingRush and Drakesbane ? I've started one for RR over there @ KI WAR forum, but need help with more sample to lessen the error%... but for Drakesbane, i can't test since i dont have drg75.

3. What do you think of this regression @ image joined ? In blue, the brute data posted in this thread, red the model from Urat, and black the one i'm proposing (Polynomial regression @ 4th degree).

[ringthree]

Fuck, I contributed to bumping an old thread. But at least the new information is interesting.

[Nightfyre]

Your regression fits the data very well, much better than urat's at low and high dDEX. You already knew that though. Unfortunately, the sample size that would be required to disprove one of the proposed equations is huge.

Not to be an asshole and present something we essentially can't prove either way, but we also have to consider this from a programming standpoint. You've got some very small decimals attached to those variables, is it not possible and potentially even probable that they wrote a floored equation (hell, they floor everything else) or an if-else string that provides the stepped data we already have? It's possible they mapped out a rough range of intended data points and then found an equation that fit the data just as we have, but I suspect they took the easy way out.

[Masamune]

yep agreed with Nighfyre, myself uses Model1 in my Excel tool.

My main interest lies mainly in the 2 first questions.

[Starr]

What crit % do you have the first hit of RR at atm?

[Masamune]

so far (RagingRush Critical Rate Test - Killing Ifrit), the % obtained isnot conclusive enough regarding the error :

@100TP, 13,80% crit rate with +-6,57% error (209 sample size).

I really hope that test not to stay at this point, but for sure i wont finish it alone, that i'm sure 100% {Please assist}

For those wondering the interest about such test on a so ol' WS, not only i found contradicting resources saying either 0% or 10% @ 100TP, but also different % @ 200/300TP, and 0 trace of the way those claimed % have been tested.
Result: huge dramalike topic @ BG signed Starr (surprised XD ?) between KJ or RR builds... which concluded by a simple yet very true comment from Mojo:
"This is reduced to determining crit% of RR @ 100TP." Hence the necrobumping of this topic.

[Starr]

It is just 13.8% crit rate or that's on top of the 24% (dDEX cap + 4/4 merits) making it 37.8%? How long do you intend to keep parsing for?

[Masamune]

go look yourself how test have been done to answer your question.

But 2nd question is a good one indeed: if the error calculation i used is correct, the test would start to show conclusive results from 400+ sample size already.

[Starr]

I already told you I am IP banned from KI, and isn't it easier to just say the answer? On KI I saw you say it was over 24% or something but I can't click the link or it will say LOLBANNED.

[CDF]

You already showed in this case that the critical hit rate bonus is non-zero, or significantly higher than 24% (assuming the base rate is 24%).

[Masamune]

Yes cdf, and that's only conclusion i could draw off it so far.

But problem now is, as i'm adding more samples, the % grew .... higher up to 16.5% this morning -.-

So i'm starting to wonder 3 things :
a) Do one of my gear used has an hidden added crit% ?
for info i used:

Weapon: Erlking Kheten non augmented
Head: Ohat
Body: SH
Hands: Seiryu Kote
Waist: Swift
Back: Boxer
Ranged: SelfBow
Ammo: Horn Arrows
Ear: Brutal
Neck: FortTorque

Used those gears because my archery is lvl22 XD, the other is to avoid getting 2TP from hit. Other slots are naked.

b) RR has indeed an high crit% @ 100TP
c) i made error(s) in calculations ?
d) Can estimated crit% drop from current value (~16.42%) down to a realistic value (~10%?) past the current range of possible values i obtained with current error (6.21%): [10.21%;22.63%].

For the moment, i'm at 240 total sample size, i'll stick to assume "yes" to option d) till i reach 385 samples, which is the maximum sample size for an hypothetic crit%=25% with 5% error, all other crit% estimations need lower sample size (for an error of 5%).
(If i wanted to go @ 3% error, max sample size would reach 1067...)

[Starr]

So we are looking at around 40% critical hit rate +/-6% roughly at the moment? Fucking sexy WS amirite?

[Masamune]

the problem i'm fearing is i hope i didnot skewed my tests modus operandi, not the actual obtained crit% value.
