The idea that you may win 52-55% would be fine. In my case, I am winning 60% of my sessions but it's because when I am in the hole, I play longer sessions (I know I should not) and often recover. My problem is that by counting sessions, I am a winner but reality is that my losing sessions are much larger and at the moment I am losing. Average winning sessions are about $800-$1k, losing are about $2.5k. Biggest winning session playing $25-$150 DD is $3.2k, losing one is $6.2k.

I too am currently taking a 3 week break.
