That is pretty damn good, IMO. I don't have PT either, but my stats are usually the same. Regardless of how long I play, be it 2 hours or 10 hours, I always see 30-35% of the flops and win 30-35% of those hands.
You are winning 16% of the hands you see. I could live with that because you are winning more hands than others at your table which is the point
