838 hands will tell you almost nothing - that's such a tiny sample.

Over 12,000 hands, I'm seeing these numbers:
VP$IP = 25.56% (that's actually higher than I'm playing though, due to 7000 hands of .10/.25 w/ 27% outweighing my current 22%)
W$WSF = 35.66%
PFR% = 5.14%
W$SD = 46.93%

The only thing that I can make any remote comments on is PFR. I tend to feel like I'm a rather reserved player (as successful NL players go). So with my PFR% being 5.14%, I'd think you'd want yours to be at least 5%. Then again, just one dry run of cards during those 838 hands could make this number pretty screwy - making your 3.34% tolerable.

I guess I'd say you should pay attention and make sure you're aggressive when you have the cards. Aside from that, build a bigger database and analyze from there
