Now just eliminate Fillies & Mares and this is in profit! Chase best tote, top fluc & Betfair odds and this has been a good earner.

So, it appears very consistent horses that are proven winners can be depended on to repeat. I initially thought they would be overbet, but there we go. This can be improved on to become a good system.
