Dex/Parry tiers - definitive testing methodology needed

[Ruckus]

I wasn't able to parse today due to moved raid times, but here is some of the data so far:

512 parry, 209 dex - 5302 hits, 1346 parries (25.39%)
512 parry, 218 dex - 5077 hits, 1252 parries (24.66%)
512 parry, 220 dex - 5151 hits, 1256 parries (24.38%)
512 parry, 225 dex - 5166 hits, 1328 parries (25.70%)
512 parry, 230 dex - 5733 hits, 1500 parries (26.16%)
512 parry, 230 dex - 10758 hits, 2722 parries (25.30%)
512 parry, 235 dex - 5338 hits, 1302 parries (24.39%)
512 parry, 240 dex - 5730 hits, 1450 parries (25.31%)
512 parry, 241 dex - 11735 hits, 3103 parries (26.44%)
512 parry, 242 dex - 5221 hits, 1371 parries (26.26%)
512 parry, 243 dex - 10071 hits, 2571 parries (25.53%)
512 parry, 244 dex - 16154 hits, 4182 parries (25.89%)
512 parry, 245 dex - 10510 hits, 2807 parries (26.70%)
512 parry, 246 dex - 5268 hits, 1406 parries (26.69%)

Testing above 246 and below 209 sometime this week. Will post results.

Im not the smartest warrior out there but i cant see any DEX "wall" or "roof" or w/ever we want to call it.

But i wonder if DEX gets checked against the target's STR (and parry against accuracy).

Do you by chance have the crits for each test? They don't show up as regular hits. May not be needed, might be helpful.

Pretty messy dataset. Can dump linear regression on it based on deviation from minimum value,

f(x) = 0.400x + 24.01
r^2 = 0.357

I'm wondering if it's a linear increase in DPS relative. I noticed that my block strength with the same shield decreased as I leveled through Toto-Rak, which suggests to me that it might be all normalized by the base level value. If so, the 512 parry would suggest a 15.99% base parry rate with base dex and base parry. Just a hypothesis -- should be easy enough to test using a weathered axe and no +dex or +parry gear.

Currently at 347 STR and 191 DEX, focusing on getting ilevel 90 tank accessories and not the ilevel 70 crafted DPS ones, I parry 23% of a hit and I seem to parry about 22% of the time according to the same model you use.. If I dropped all my tank accessories (assuming all ilevel 90) I would sacrifice 25 VIT and 15 Parry (this includes melds into DPS accessories) to gain 2% more parry mit and roughly 5% increased parry chance which is basically .1% flat mitigation? I can see getting STR and some DPS stats for damage/enmity and self healing, but DEX seems like a giant waste of points just to increase the chance that you mitigate a % of a single hit at least Parry just inherently comes on tanking gear. I highly doubt that full ilevel 70 crafted accessories melded for tanking will net the same effective HP a tank has with pure tank gear.

If you just look at the 25 VIT alone, the DPS accessory setup needs to equate to 6.104% more mitigation just to equalize the loss in the VIT, as far as effective HP goes. Obviously that isn't coming from the Parry boosts, not sure on the self heals, that could use some testing.

It's a step function so your linear regression isn't going to look good.

Is there any evidence there of a step function? I certainly don't see any in that data or in any data previously collected.

//EDIT: Data visualized:



See anything there suggesting a step anywhere?

Everything in this game that has been analyzed has worked as a step function. While it may not necessarily be true that this follows, you should know better when dealing with probabilities than to use the method you are using.

Yes, I do see evidence of step function here. There appears to be a significant break with the testing around 240ish. The only issue is whether there is a second break point earlier (which I don't think there is anymore, but Niinjitsu's data indicated there likely was). You do understand that the we're going to see a roughly normal distribution (trials aren't held constant) about the expected value right?

Are you telling me what you showed doesn't look like a step function? Because it most certainly does.

Unfortunately not. I am parsing all tonight. I plan to do several 1k trials at each dex point per your previous post. I will record the crits this time.

Any other suggestions before I kick it off?

Looks like a step function. From how it appears, it looks like 14 Dex increments starting from 211 to reach the next % level.

The 209 run is a little strange unless 24% is the floor.

211 - 24%
225 - 25%
239 - 26%
253 - 27%
