I worked this out for me the other day. It all depends on blind levels to be honest, and how they go up.
Heres by stats for parsdise...
10 $33 SnGs
blind levels - 5/10, 10/20, 15/30, 30/60, 50/100, 100/200, 250/500, 500/1000
The everage hands it took to finish it was 76. The average hands per tourney i played was 69.
I won 6, came third 4 times. Thats one hell os a VPIP or whatever it is on tracker
