Ok i hit the lab, and i got one.
its 37% before the stack damage and Acid Blood assuming you keep them there. if you can grab them after its 52%
B11U4,D1,NJP,U3,33 xx Acid Blood- into (LB/L1- or F13 xx EX Tail Flip combo starter, to stop jump out or B3 xx EX Tail Flip to stop Normal string punish on F13 guess.)
so in this case i made: B11U4,D1,NJP,U3,33 xx Acid Blood - 37% Easy Restand its Plus 2 after Acid Blood (Throw Forward for 52%)
if you optimize it i will replace mine. or add it as a better one.
also noticed this might work for the combos that are hard on Female characters, like the:
B3 xx EX Tail Flip,U3,NJP,U3,33 xx Acid Blood
those 2 U3 combos are hard to land the NJP on Females cuz there Small Hitbox, maybe you have the solution or another idea, ill hit the lab as well.
