playing stats - what is good?

i play at pokerstars, and they have stats they keep track of for each session while i play.


Consider a full table of hold'em.....


what is a good percentage of hands to play....i aim for around 38%...i am generally a breakeven player in long run.


Is that too tight or too loose? Also, i seem to win about 60-65% of showdowns, which i think (need opinions here) is pretty good. Of course showdowns don't include the hands i play to river and fold, so that doesnt mean i win over 60% of the hands i go for
