I decided to try and build my bankroll through micro heads up SnGs, mostly turbos, because they are rather quick.

Out of a sample size of 20 SnG's, what should my win % be ?

Right now my % is 65% win 35% lose. Is this good enough or do I need to alter my strategy in some way?

Right now im basically playing very tight for the first 1-3 levels, playing only big hands... when the blinds get to 200, I start pushing a wide range of hands, and it seems to work well enough.

Should I tighten up my game a bit to try and improve my Win % or is the loose style in these Turbo SnG's and my 65 win percentage good enough?

Thankyou
