Yeah I think that might be unnecessarily complicating things. Really, dollars won is most important. It's not most important if everyone's having different amounts on, but when we're all just having $1 on each selection, then it's the MOULA in the POCKET which counts!

Example:

Person A has had 100 bets, 20 winners, collect 120, for a lovely 20 unit profit.

Person B has had only 10 bets, for 2 winners, collect 13, for a 3 unit profit.

In my book, person A has gone better, however if we used %POT then Person B has gone better, even though person B's profit is very small and able to be eroded with just a couple of losers, whereas Person A could have 20 losers in a row and still not be losing.

That's why I'll go with $$ profit as the criteria for the leaderboard.
