I really don't know, if you could test it, it's f4, roll, njp, b12, 1+3, dd2 = 32%
Now it does like 28%.
I actually get 27% for that, although with b21 3+4 i get 28%
however if you do f4, roll, b3, tpkick air sai b12 1+3 you will get 32%
For posterity these are my BnB's from the other day
123, roll, b3, tpkick air sai, b21 1+3 = 34%
b12 roll, b3, tpkick air sai, b21 1+3 = 34%
roll, b3, tpkick air sai, b21 1+3 = 29%
ex tp kick, f23 roll, b21 2+4 = 34%
ex roll, dash under, njp, b21, 2+4 =27%
f343, tp kick air sai, f2 roll, b21 3+4 = 41%
These are the same damage pre patch and post patch anyway.
