Hi Cairns ,

If you had dutched say to profit $100 per race

Kens double @ 2.30 outlay $77 lost $77

Dark Target @ 1.50 outlay $200 won $100

Stavka @ 2.50 outlay $145 return $362
Threedee @ 5.60 outlay $65
Apple Lode @ 6.90 outlay $52 profit with stavka winning $100

This using really bad unitab dives puts you up $123

with that 19 figure in my original post thats just the total of the ratings of the 4 horses i selected ...you could use your own method with the 100 to 121 ratings and just use the same principal..
