I haven't had time to go through it in detail yet but there is one big thing that bothers me. Everyone knows that backing tote favourites to win indiscriminately is a sure way to lose money - usually about 15% LOT. Now even staking plan advocates generally agree that for a staking plan to work you must start with a system that breaks-even at level stakes (or at worst gives a loss of a few %). Now what is so special about this that it can turn a loss of 15% into a profit of 8%? On first glance it seems a bit much to expect. As I said I haven't looked at in detail yet but I would not use it without some thorough testing.
