ROR Again . . .

[James989]

For a fix Bankroll, B , If bet 1 hand with bet size $100, ROR = 13.53% :-

1) Then If bet 2 hands with each hand bet size $73, ROR = 13.53%
2) If bet 2 hands with each hand bet size $50, ROR = e^(-2 * 73/50) = 5.39% ?

I think 1) should be correct, how about 2) ?

Yes and yes.

Thanks Don

1) How did the 13,5% risk of ruin became the norm?
2) Is it the optimal number for bankroll growth vs the risk of ruin?

Remember that 13.5% ROR is at full Kelly with no resizing. If you resize down when you lose 1/3 of your bankroll or extract your winnings when you reach some preset goal your actual ROR is different.
