here's one instance where i use PAhud stats for floating ...

example

say player A (A tag 20/10 pfr) raise s4xbb ..
you Player B call in position with 44...

you look at your stats and you see Player A has an AF of 4 on the flop but an AF of 1 on the turn ....he makes a standard Cbet on the flop unless the flop is super scary or has a bunch of face cards ...this is an instacall ....
