Yah I know that is part of it but also I think at $1/2 NL you can play a pretty low variance style. I don't seek out 52/48 % +EV plays. I usually play pretty solid and TAG and wait for other people to make mistakes. The garbage I see people call with PF at $1/2 makes me sick I feel like a competent player should win every session if they are willing to play with 3 BI's per session.
