Hello, Don & Experts,

Is there a formula, website, or simple rule(s) of thumb, for determining the chance of being ahead vs time played (or # hands played)? Don's book gives an excellent discussion of Risk of Ruin and calculations for a given bank roll, edge, std dev, plus # hands played. I was just curious of the other side of the "equation" - "Risk" of Return...

I also recall some place in Uston's book that for a given edge (e.g. +1.5%, 100 hands/hr), the % chance of being ahead was 67% after 10 hrs, and 73% after 20 hrs. I don't recall whether 2d vs 6d, table rules, etc. Sorry!

Thank you for your help.
