Shaun your talking about backing the same horse everytime it races you never mentioned that you wouldnt bet if that horse ran out of form or drew a bad barrier. Of course horseracing and roulette are vastly different but the principle behind my arguement was the same. You will probably be successful in making a profit for a period of time but when it comes to a stage where you pick a horse that has a run of losing for say 15 starts all the profits you made will be chewed up just like what happens if you consistently back a color in roulette to gain a set profit, eventually you will hit a run of the other color that will send you broke. However its your money not mine i'm just having my two cents worth.
