Given the limited ability to make conclusions just from the stats, here are my suggestions:
1. Loosen up in the hj, co, and btn (16% vp$ip is pretty tight).
2. I think "went to showdown" should be in the 30-35% range-- you are getting too much respect because of 16%^^ or are playing too weak tight and folding winners too often.
3. It's interesting that your aggression escalates (flop < turn < river)-- seems like it should be the opposite to me: there should be more times where raise on earlier streets for information, or on a semi-
bluff draw, and where you check down the river in position with a marginal hand, rather than the opposite.
Hope that helps!?!
