Disagree - at this level I'd say a VP$IP of 25% is about perfect. If you play more marginal hands with a bit of skill on weak tables they can be extremely profitable, as long as you know when to bail out of hands.

My stats show that I've gone to showdown 28% of the time (compared to your 20%) and won 55% (compared to your 54%). My VP$IP is 28 after 9,000 hands, fwiw, and I'm happy enough with that.
