Say we are playing some loss Rebate promo. If we deposit 10k, we got 19% back. Based on computer simulation result, if we bet 2000$ each hand on banker in Baccarat and play until we play hit near 4k profit, or leave when we lose whole 10k deposit to get 1900$ loss rebate, the EV for this promo playing is about 320$. The chance to leave with 14k(10K deposit+4k profit) is 70% , the chance to bust and get 1900$ rebate is 30%.

So we have 10 unit of buyin, what is the ROR for this play? Also, if we need the ROR below 5%, how many buyin do we need? what about 2% ROR?

Another way to play this is to play until we hit 8k profit which is optimal EV wise, the chance of winning (leave with 18k) is about 50%(pw), chance of bust(leaving with 1.9k lost rebate) is also 50%(pl). The EV for each deposit/play is about 520$. What is the ROR for this play if we have 10 buyin? Also, if we need the ROR below 5%, how many buyin do we need?

thanks a lot in advance!
