I just finished BJA3, and learned for the first time about SCORE, which is a wonderful way to account for both risk and reward in a standardized way. Now it does say in the book that by using CV software I can easily adjust the ROR from 13.5% to anything I want, but for now I was just wondering if there is an easy mathematical fix I can do by hand, since I don't have the software yet.

(The reason I don't have it yet is because I have a Mac, and as far as I know the Casino Veritas software is NOT Mac compatible, right? Does anyone know if there are any plans to make it compatible? I saw another thread from 4 years ago that suggested both buying a separate PC or buying something called Parallels for Mac. Are these still my only options?).

So here is my question:

Is there a simple relationship between bankroll and ROR that I can use to manually calculate the bankroll required to lower 13.5% ROR down to 5% or 2% or 1% or whatever I want? For example what does doubling the bankroll from $10,000 to $20,000 do to the ROR? Thanks.
