I think aPat sucks to be honest. All he does is 66 B and 3 3 B. Maybe its just me because I've destroyed so many aPats with aGIs before. The only Pyrrha thats ever given me trouble is Xeph's. You can do it, its not impossible.
That would require too much time haha. Also some match ups are just impossible to be good at unless you invest a lot of time. Like, learning to react to pyrrha's godlike mixups and oki, or against aPat.
