I have found the following four states to be extremely stable. These are the best states for my systems because these states tend to favor singles. You will see MANY power numbers hitting in these states. Power numbers represent the core of the game (sum 9 to 18 numbers; the basic bread and butter numbers in Pick 3). After a double hits, you will notice that the game quickly goes back to a steady stream of singles. The Super List is good for these states too because List 80 includes the 40 power numbers.  Wisconsin is the best of the four so I have it listed first. Second best is Arizona, followed by Kansas and Louisiana.
