It depends on the game. At 0.5/1 I was about 18/9, and the tables were generally 4 to the flop. At 1/2 I'm about 17/11, with the increased PFR due to the ability to isolate loose limpers. Your PFR will be high on tables where you can isolate, and on really loose tables (7 to the flop type where you can raise many suited hands for value in late position after lots of limpers). Don't explicitly try to play looser for the sake of playing looser, but do realize where some marginal edges that you may be passing up exist.
