I did some back testing this morning and found some interesting results.
Starting with the oldest draw, enter 4 draws, oldest to newest. Click on "Git em'" and you'll have your first set of numbers. In the 16 boxes, look in the right lower corner. One pair for the next Pick 4 is usually in that box. I've back tested Ohio and Missouri, and the results are surprisingly consistent.
Now, Sniff Left, then Sniff Center. In the "Sniff Center" set, 3rd column of numbers, 2nd or 3rd or 4th row, your number is in there!! Some sets of numbers have me adding +1 or subtracting -2, or even +5 in a couple of tests. When both states I tested had triples within the 4 draws tested, the results weren't that good. Doubles seemed to do a lot better.

The results seem to end up in the "Sniff Center" set of numbers. Do some research for your state. So far, this works well for Ohio and Missouri. I hope this helps with some direction.
