I found a $25 50/10/6 DDB video poker game, which pays back 100.06%. Factoring in 0.1% value added by RCs, and the free play generated, this seems like a decent game to make some money at. ($100 an hour before any free play, @ 500 hands per hour)

My question, how do i calulate a bankroll that i would need for this game? How do i find my ror for different bankroll sizes? Its going to be a large number, but i dont know how to calculate any numbers i would need to not go broke playing this big $125 per hand game...
