It looks like you have the same VPIP for nearly all positions....
This is probably costing some $$, play more hands in later position and tighten up in EP and raise more when you do go into a pot, dont just limp. I think your vpip/pfr gap is just a bit too large in the EP&MP spots.

But hey, you're winning, just fine tune a few things and I'm sure your win rate will grow even better, good luck.
