winrate by position without including rake (and without blinds) is critical for comparing statistics among positions.
I want to ask a question like "how does river call efficiency predict winrate by position?" but because rake changes by the number of players @ the table its very difficult to tell if a change in winrate is due to a change in rake OR a change in my play.
This translates to all stats. When rake changes by # of players at the table you can't determine how a stat influences winrate by position UNTIL rake is factored out.
Taking out blinds just allows me to save on some mental arithmetic.
please include this stat for future updates.
