I have been developing a system based on RP top speed rated horses which were 3rd LTO. It probably isn't unique but after 100 bets i want to check it with a reliable database such as the Adrian Massey one. After 100 bets, £1 level stakes, win only, has returned 32%. Does anyone else have a similar system? Does anyone know of a reliable system builder that I can input my variables in order to test it over a longer period? Thanks. Steve
