It's truncated at each step, just so you know.
1.87*11.1 = 20.7, 20.7*4 = 82.8
Glad you noticed this. I was waiting for someone to point it out.
If you see my earlier post, I mentioned to round down to nearest digit on fractions, but then I forgot my Kaiten AM testings. They contradict each other.
I was testing this on fortifications. Using minimum haste (easier to see normal attack animation) I removed multi-attack gear, TP-conserve gear (WS). I subbed /blm. No Hasso.
TP Set:
Phorcys Salade (5), Hagneia (3), Unkai Body +2 (10), Rajas (5), Brutal (1), Tyrant (4), Misuuchi (3), Goading (5) instead of Rose/Unkai earring, Unkai Legs+2 (7), Ace's feet (5).
WS Set: Rajas (5)
With AM active Atheling]=> Misuuchi & Mars]=> Tyrant.
I wanted 30 x controlled tests where Zanshin/Ikoshoten didn't interfere. They rebuild @100 TP. Anytime Zanshin/Ikoshoten proc'd, I'd just reset cycle, and wait for AM to wear off.
To make sure, I redid this test 30 times in Sauromugue Champaign.
(This test was annoying since if I got hit, I would have to restart whole cycle.)
This time with normal TP/WS gear.
It came out @100 TP aswell.
If the fractions were truncated, it wouldn't rebuild @100 TP.
I don't know what to make of it, feel free to test this out yourself if you got access to Amano/test server. Maybe I overlooked something here.
