I believe in 1 digit repeating from the previous draw....percentage wise this is true.
I will give an example now of how to position that number.
Example: Michigan evening yesterday...651....
I would take the 6 (the first digit) and the next night's draw bring it straight down and 1 over..............so for the next night's draw if you think it would contain a 6 would be in positions 1 and 2. (example: 6xx, x6x). So you can eliminate the number 6 in the 3rd position.
The 5....the middle digit can go any 3 ways.........so now we have as an example if you think a 5 would be drawn would be in position 1, 2 or 3........(example: 5xx, x5x, xx5).
The 1 in the 3rd position if you think a 1 is gonna come in....would be in the middle position or the 3rd position...(example: x3x, xx3).
Now back to that 651 number: If I used the above theory and I thought a 6 would come in...........I would play the 6 in the first position or the 2nd position...............763 was drawn. The 6 ended up in that second position.
Check out your state and see if that works. Sometimes this theory comes from the same day from the week before. But in Michigan it is the day before.
I got this information years back from a gal in western Michigan who was a beta tester for Gail Howard. I lost track of her thru the years; I wish I would run across her again. If you are out there, please contact me.........lol. I also wonder why Gail Howard never put out her Pick3 program. I know it was being beta tested.
