conflict between pp stat box and poker tracker???

[redbeard]

i'm probably just an idiot, but can anyone explain the difference my poker tracker stat box won $ when saw flop and the won $ when saw flop on poker tracker. at the end of each session i write down my party poker stat box and for my last 14 sessions the won$ when saw flop average is 37% (i know i'm running cold), with only one session over 40%. yet in poker tracker over the same period it says my won $ when saw flop is 41.25%. to me this math doesn't add up. is it possible that there is a different formula these two entities use to calculate the win %. or is there possibly a glich in my poker tracker (i downloaded the most recent patch when it came out)?
