Miff-- trust me on this one. There are different versions of this, but it is a betting program, not a handicapping program. The biggest element is the 10% rebate. The program still has to get projected odds from somewhere. If you are good enough to lose only 5% against a full takeout (which is well above average), and the program makes your bets more efficient (probably wiping out the other 5%), then the rebate will give you a profit of 10% on handle. For the record, Wagner, who is one of the biggest (200 million handle annualy) works on about 7% after huge rebates, with a team of handicappers.
If you are minus 20% (average), the program won\'t help you either way, with the rebate you will be minus 10. But if you are -30, the program will maximize your results in the other direction, and the rebate won\'t save you.
And to work out the right odds on every horse in every race on a card (even your own right odds, which can be wrong by a lot) involves a whole lot more work than most people are willing to do.
