Feedback.....absolutely flawed in any racing or punting logic.....you will never make racing profit trying to dream up such methods. the easiest thing to accompish in racing is a backfitting of results to a set of rules that shows great potential or profit. System developers and sellers make their living by that from unsuspecting and uneducated punters. Read some of the excellent material on the Pro-Punter site re: systems and **********. Although your not scamming anyone, these types of methods of trying to find winners are the same.
