So chrisbcritter started watching my operation and I had seen a EV graph that I posted. He had noticed that for the last 40k hands something has changed in my game. Ive pulled all of my position stats for the winning period and for the period where I am not winning as much. Can anyone tell me for these stats posted if there is something obvious that has changed, and how the hell I correct it.
