I have purchased his systems one the wynteck and wynmaster.they didn't work for me but just like pick-4_master said they're a good tool to help in your picking strategy I have found a way of modifying it to help me win in the 3 positional values.
I don't have the p-4 master cash system, but I do have the master cash p-3. It's nothing to write home about. It would work much better if it was updated once a year, and was customized for each state.
He does have a plan for individual states, which you can sign up for. I think it costs $300.00 for one year, and he sends you some numbers every two weeks, after analyzing your state.
