I'm going with both anyway, but I was wondering exactly how the new Hurricane hypers worked.

Hurricane's base damage is 300%
Hurricane- Reinforce (hyper): "Damage +20%".
First question. Does this mean Cane+Reinforce is 320% (300%+20%) or 360% (300+.2x300)?


Hurricane- Split Attack (hyper): "Number of Attacks +1, reduces Damage to 65% of the original Damage"
Second question. Does this mean [(300x.65)x1.2]x2 for 234%x2=468%
Or does it mean [(300x.65)+(300x.2)] for 255%x2 510%


tl;dr
Does Hurricane -Reinforce multiply or add in?

I figured I should ask before trying to test it myself, which can be difficult with AFA on low-level (no PDR) mobs and such a small variance in possibilities.
