In Playing Blackjack as a Business, Revere advocates dividing the total bankroll into four, thirty unit session bankrolls and, playing until the session bankroll is doubled or lost. I have read the current authoritative advice on money management and realize this is not even close to being accurate advice to maximize profit while minimizing risk. i.e.: One should have a minimum bankroll of 100 MAX bets to minimize the possibility of negative variance tapping them out.

What is the ROR if one plays with four, thirty unit bankrolls until each is doubled or lost as Revere published?

Maybe a better way to ask this question is: What is the probability of losing 4 consecutive thirty unit bankrolls at an average game spreading 1-6?

And this two part question is speculative:

Did Revere believe that having a 20 max bet bankroll was sufficient to beat the game in the long run?

Or was this sound advice when he was playing because the average game was far more favorable to the counter?

Thanks for any answers/opinions/comments!
