Midas, you know there is some merit in that one as, as you say it has to be duplicated, the problem though (yes there is always a problem) is that you need to back 1 dog in race 2, 2 dogs (maybe), in race 3 ,. 4 dogs inrace 4 etc etc until yes 1 has. to duplicate if covering to win your bets would be up in the $100,000,s by race 8 and they would all be 10 to 1 on, but still you would have to back the winner!

An alternative is that my old man (a dogs man from way back) reckons that USUALLY, whatever trap wins twice will win 3 times (at least) so there is a basis of a system................and a maximum of 6 bets per meeting!
