Two people just asked me if I have anything for Pick 4 Doubles. Here is what I came up with (I will work on this myself when I have the time).

Divide the 360 doubles into 10 groups of 36 numbers each. Now look at the most recent double that hit your state (say its 0025). Remove the group that has this double (the first one below).

Then look at the previous double that hit.
Remove the group that has that number.

Keep removing groups until you are down to 3 groups. Only focus on these doubles because one of them will hit soon! (Do NOT go down to the last due group because it can take forever for that group to hit; focus on the 3 most due groups).
