So guys, here are my winrates by position over the last 50k hands. I realize SB and particularly BB could be better, but those are often quite complicated to fix and caused by a variety of factors. My primary concern here is the BTN since this, I believe, should be the bread and butter of our poker game. I think my CO winrate is fine, but if I'm not mistaken my BTN winrate should really be considerably higher, something like 35bb/100 or better. I picked the last 50k hands for this sample, but I believe this trend has been apparent in my game for longer.

I realize this data is far from sufficient to solve the issue, so please let me know what information you would like to see to bust this leak!
