I use Nr of Hands, Saw Flop %, Flop-Turn %, PF Raise %, Vol. $ Put in Pot %, Turn-River %, Raised Flop %, Folded River Bet To %. I also tend to heavily use the player ratings in certain situations such as all-ins, overbets etc. It has not changed my play, but it has complimented it and has paid for itself 5x over.
