Puntz, just spitballing an idea here, but could you dutch those 3 selections so that its like having a singular bet that has a set profit no matter which horse wins which would help you determine your average odds for use of the retirement staking plan?

I haven't looked at the retirement staking plan for a while so can't 100% remember how the staking size is determined by I seem to remember it basically revolved around avg odds.

For example:

Horse A: $5.00 Odds (20.00%)
Horse B: $6.50 Odds (15.38%)
Horse C: $9.00 Odds (11.11%)

% chance of winning 46.50% or $2.15 odds.

Basically your turning each dutch bet into a singular bet for recording purposes and whatever the staking it suggests for the next race is, you use that for the total of your dutch stake for that race and so on.

Does that possibly meet what your after?
