I used to use it, but it doesn't really do much for me. I see ppl who freak out and think they have to change their whole game cuz their w/r has dropped the last 10k hands and just laugh. You have to get in a TON of hands for the individual hand stats to mean anything, and I can tell on my own if I'm a winner after 20k hands. I'd much rather use it to see what OTHER ppl play like. After you get like 2k hands with someone you can pretty much say what their PF raising range is (granted they haven't changed their style), and how they play stuff like missed overs and pp's.
