You didn't say if this was for online play, B&M, or home games. But I will assume online:
OK, if you played 600 $11 WTA sit and gos, with $1 of that being the buy-in fee, and you won 1/6th of them, or 100 out of 600, your winnings would be $6,000. You would have paid $6,600 to buy in to those games. So winning one out of six games would net you a loss of $600 just because of the vig. To break even you would have to win 110 out of 600 games.
Assuming you were all equal in talent, breaking even is your best hope. If you have an edge, then I suppose you have +EV.
