very low winrate at the BTN

So you have a 0.24bb/hand so that would be 24bb/100 winrate, right?

It is a bit low but it has a lot to do with the sample size. It looks like your CO winrate would be 85bb/100 and MP&EP over 40bb/100 and those numbers are a bit high :f_biggrin::f_biggrin: You would have to play at least 100k hands before you start getting some idea of your overall winrate and to get good positional winrates you need even more of course.
I suggest you wait until you have at least 10k hands per position (60k hands total) and then check again how things have developed. You might see some big differences.

There are some stats that help figure out what is going on but as you already guessed, those are not meaningful in this sample. The stats you see now probably are very much different after just 10k more hands.

My suggestion is that you keep on playing and studying and then after you have a bit bigger sample you can start looking for possible leaks that you can plug.

Thanks!
I will just check again, when my samplesize is bigger!
