Moeee, well , as exercise on those particular selections, betting to prices I invested $1144 and got a POT of 13.6%, so I invested an AVERAGE of 54.47c per race.

So now then I invest $54.47c per selection on all 21, and get back $1243.55c,

i.e. a flat stakes profit of $99.55 a POT of 8.7%

It will be interesting to see the results from Lomaca, but I am now convinced the answer lies in the fact that the lower the price is always the higher the S/R, so you lose less on the failures of the higher priced nags.

This is completely different to a staking plan whereby you are investing different amounts based purely on whether the previous few selections were successful or not, which of course has no bearing on whether the next one will win.
