I have been playing 5/10 and 10/20 limit for about 9 months now and overall, doing fairly well, winning about 1.5 BB/hr. My question is, if I allocate approx 4 hrs a day to playing, so at current win rate, would win about 6 bb, then if I win big early (say 10bb), should I just quit and call it a day. Over time, am I going to go back to the mean and land up losing some so that after 4 hrs, I am back to 6 bb.
