It's safe to say that right now, these results seem to be about RNG.
ilv83 Flank Only VS ilv88 Flank Only
AA (18% crit) AA (24% crit)
SP (23% crit) SP (14% crit)
DK (37% crit) DK (15% crit)
TwS (10% crit) TwS (15% crit)
HF (50% crit) HF (33% crit)
StP (10% crit) StP (0% crit) *also only used once...weird*
Aside from Twin Snakes and Auto, you were consistly MUCH higher on your crits than I strike-for-strike, and that could definitely have a hand in the DPS numbers.
Now I'd like to look at min/max/med
ilv83 Flank only VS ilv88 Flank only
MAX-MED-MIN MAX-MED-MIN
AA (343-218-144) AA (327-203-136)
SP (708-419-358) SP (679-404-244)
DK (548-363-306) DK (547-337-268)
TwS (479-327-261) TwS (525-309-288)
HF (577-508-352) HF (583-411-403)
This data probably isn't the best since I didn't crit s often, didn't give me the opportunity to get higher numbers as much. However, I did have a higher Twin Snakes and Howling Fist that you at my maximum; which means I should be capable of doing the same for all other strikes and sources of damage.
This makes me think there could be some sort of DET soft-cap like 325 or so. Since I haven't hit it yet, I will consistently have lower strikes.
I would really appreciate if more people post'd their dummy parses as well. Flank only or not, but with enough detail that some of it can be at least analyzed. Thank you.
PS: Since I crited more often on Twin Snakes, it sort of makes sense why that one would have a higher top value than yours, Esca. Thanks again for providing data, if you'd like to share more, I would really appreciate it. That or people can further discuss if there even is something like a Determination soft-cap.
