hey there. wish we had a little more info on what stakes you play exactly, you said you play microstakes, however this goes from 2nl to 25nl and it surely aint the same thing.
on the other hand, i play mainly 6 max at 5nl and these are my stats:
Vol. Put $ In Pot 13.18
Raised Preflop 10.04
BB Won Per Hand 6.69
i hope you know what these numbers stand for. anyway, tight preflop works for me, a 6.69bb/100 is not bad especially for 6 max. people say i am too tight but as far as i am concerned as long as i am making a good profit i wont be changing much.
you can see more of my stats here if you are interested:
