Hi Dale,
I have come across a similar stat

Based on 60,000 races.

For instance.
UniTAB 100 ptrs that are overlapped with the Radio TAB selections.

Percentage Return on Investment (RTO) of Radio TAB top 3 & 100pts
Example .91 means 91% ret on 100% = -9% Loss.

100pts and
RadioTAB-------------------W ----Plc ----Diff
1st. 66% Plc SR -----------.85--- .91 ----6pts
2nd. 59% Plc SR--------.-- .87 -- .92 ----5pts
3rd. 52% Plc SR----------- .83 -.- .87 ----4pts

Place staking plan that may work.

Black Box Staking Plan.
Increase bet by 1 unit after every 2nd successful bet, until in profit .
Then start again .
Example
1 1p 1 1 1p 2p 2p 3 3 3 3p 3 3p 4p 4 ect
