KO Bankroll Question

I use the KO Preferred system and wanted to know what BET SPREAD and BANKROLL I would need to use to earn $25/hr in the long run with a 20% ROR??? I would be playing the 8 deck Atlantic City game.

Lets assume the minimum bet is $15/hand(I can only play on weekends when table minimums are higher). The game would be your standard 8 deck AC game with about 70% penetration and really lousy rules like no resplitting of pairs.

I suppose I can incorportate the wong-out strategy used in the Knock-Out BJ if you guys think that would enhance my SCORE or EV.

Can somebody please offer some insight?
