Sorry - wrong forum I think
There have been lots of systems devised in this forum over time. Many forumites have checked through their records and tested them and have come up with %ages. win/loss ratios and what have you. But it seems to me that the tests have been "across the board" - as in thousands of races in all states & venues. My question to members is has anyone tested systems on a per track basis. Something along the lines that a system is (say) based on horses starting from barrier 1, and have a strike rate of 40% or better wins 60% of the time at all tracks - but at Caulfield that percentage climbs to 75%, or on the other hand it is only 20% at Rosehill. I would be interested if anyone has checked these details in depth. It might be that of the many ides put forward here there are some that could pay consistently - but I don't know
