%won at showdown & %won w/o showdown.

[DumbKnob]

Hi, I just requested my stats from PokerStars, just to see what kind of stats they will give me. I saw it's pretty basic stats. But I was wondering about the last 2, which is pots won at showdown and pots won without showdown.

Obviously I know what they mean. But I was wondering if I should be aiming for a certain % for pots won at showdown? As in, if I'm only winning about 40% of the hands that I play until showdown, is this a bad sign? Does it mean I'm calling too much at river? What % should I be aiming for?

And for the number of pots won without showdown, if the number is really low compared to the number of hands played, does this mean I'm not playing aggressively enough to push people out of the pot?

I'm playing microstakes limit, btw. Thanks.
