Oh wow -4? that's even worse. I would get jabbed out of it from time to time against certain ones. It's like you have to perform a early buffer as soon as you let go of the guard to out prioritize. Cases such as SSP and then performing P6P so it's like wat? lol. Good call though.

It's the same case for PP6P, the real move you have to look out for is 9P, it's -1 (depending on the spacing it can be +0, if you're really lucky even +1) and it also recovers just as fast, that move is a legit frame trap.
