Shaun, this smacks a bit of the old hot pots system, although there were a few more rules as I remember, and most importantly it was betting to WIN only,I did in 2 banks of $2000 each backing level stakes. Just a constant small loss on T/O. The initial selection though was Pre Post Favourite, and best results came fvrom thr racing radio prices.
I'm not knocking the idea totally, I always thought that it had potential especially for the place. I did some restospective research afterwards and found a profit if the bets were restricted to Saturdays, Wednesdays AND DUEL winners i.e. only bet if the contender had won its last 2 races.
