Agree 100% CP.
I take note of those stats and I also use short-term stats. eg yesterday on Syd, Melb, Gold Coast races up to race 6 there had been 7 favs & 10 in-the-market winners, this told me that some "bolters" were overdue and so I laid accordingly. Races 7 & 8 at those meetings were won by 1 fav and 5 good priced winners....thank you. Of course it's not alwasy that simple but it helps to know roughly where you're at.
