Nice article.

HEM is good for this - comparing winnings with $EV adjusted winnings over a large (100k hands++++) sample size. I look at this sometimes when I have a session where I run like 5 buyins below EV, or a fortnight where i run 12 buyins behind (both happened in september)

i should probably run stats on returns filtered by pots where i got it in ahead, vs those where I got it in behind though..
