What I used to do was to emphasize all my keytaps to make sure they're all on beat. It'll definitely help your PA on slower sections, but you can't really do this on fast runs like a 32nd roll or something. Another thing I suggest is to download Stepmania and work on your MA. Once you start getting minimal amounts of greats, come back to FFR and the PA window will seem a lot more lenient than Stepmania.

Hope this helps!
