I actually purchased one of his systems and found errors in the draw histories that were used. Was it an honest error or was it an error to make the system look profitable. But these were results from the Tri-State Pick 3. I've back tested other Pick 3 systems and were not profitable.
Maybe they work in some states and not others.
If you won then congratulations. My question or red flag is why there are so many Pick 3 systems?? Would you need to purchase all of them just to see which one is profitable?
