It’s not clear what kind of ROR you’re interested in, Sylvia. Since 10/7 DDB is a positive game, you might be wondering how much money you need to play the game forever. (“long-term ROR”) Or, you might be wanting to know the ROR for something like 5 hours of play. (“short-term ROR”)
Looking at longterm ROR first…for $5 100.07% DDB with 0.1% CB, with a bankroll of $718,900 you’d have a 10% ROR. The long-term bankroll for a 1% ROR is twice the long-term bankroll for 10% ROR. So a bankroll of $1.44 Million still has a 1% chance of not being enough to play $5 DDB indefinitely.
If you decide that the comps and bounceback add another 0.1% to the value of play (i.e., 0.2% total including cashback), then the bankroll required for a 10% ROR is reduced to $446,550. And twice that amount for a 1% ROR.
What if you want to just play for several hours? Say, 3,000 hands. How much money do you need? For a short-term ROR of 10%, you’d need to start with $10,500. To have just a 1% ROR, you’d need $14,500. (Those short-term calculations are not very sensitive to the amount of cashback. The difference between 0.1% and 0.2% CB for 3000 hands is $75, or 3 bets. So small changes in CB have little effect on your short-term ROR for several hours of play.)

I never learned this game because I heard it was complicated and very few casinos offer full pay. I think I found a 100.07% one with some cash back and comps- not sure about the rate. Problem is that it is only available in $5. Now I know the volatility is going to be very high. I know there is a site somewhere that can calculate ROR. Could someone remind me what the site is? I am going to check it out later today and make sure I wrote down the correct pay table and I will try and find out the cash back rate. I know my friend also gets some freeplay in the mail. She has $100 for today but again, I have no idea what this is based on.
