Have been working with wheels for the Pick-3 for the past week. I started by using the hottest 5 numbers from the past 20 draws. What I found by doing this was that I was consistently getting 2 numbers right, but almost always missing the third digit. I took those same draws and went back and used the past "15" draws instead and the results were dramatically better. For the next week I will be using the hottest 5 digits from the previous 15 draws and we'll see if the results are any better.
