It only works on races that pay 1-2-3, ie 8 or more runners, but I did have a good win only through playing the %.
My bets were Sunday Joy 1000/40, Royal Purler 1000/40, Sierra Dane 900/30 & Ms Bowie 1000/50. Outlay 160, return 1040, not bad for 15 minutes work. Gotta love odds on favs. Here's one for quapi, SR1 Hawkes has 2 first starters, one at 9/10 & the other at 11/1, who would be stupid enough to back the favourite??? we all know the result.
