Don't beat yourself up too bad, it IS gambling, hopefully at a profit. I am intrigued with MPH Pro because it is web based so I can use on my Apple laptop or even my iPad. But there is no support I know of--like we have with Ted plus RDSS is more robust.
I'm re-reading Modern Pace Handicapping for the 3rd time, hoping more will sink into my aging brain.
Best of luck, stay in touch.
