After months of fiddling with my own methods and programming attempts, and losing more money than I care to admit... I got (and read) a copy of Modern Pace Handicapping, and got RDSS2.
Tonight was my first night using it. 8 for 16 bets, 68% ROI.
Hopefully this wasn't just pure dumb luck... I'd like to be able to pay the subscription out of future winnings.
