This is a simple system that you subtact from the last number. I've seen two straight hits in Florida in two months with eve to mid and 2 straight hits from eve to eve and mid to mid. In my Florida test, mid to eve and eve to mid showed more split pairs and front/back pairs than eve to eve or mid to mid.
Florida straight example, mid to eve,
Saturday Dec. 18 mid.............157...................eve-461
Sunday Dec. 19....mid..............516....................eve-316
If you subtract 461 from 157 using individual digits you get 316
4-1=3
6-5=1
7-1=6
316

Most of the time you'll get pairs, but it's relatively cheap to play. What I like to do is to do 8 or so draws back since some of the workouts produce pairs and straight/box hits down the road. When a new winning number comes in, you do the workout for the new winning number and erase the oldest number on your list and play the new set.
Eve to eve example:
Monday Nov.8.....................mid.- 303...............eve-136
Tuesday Nov. 9..................mid-905.................eve-854
Wednesday Nov. 10.........mid-068..................eve-713
Thursday Nov. 11..............mid-601...................eve-121
Friday Nov. 12...................mid-722..................eve-963
If you subtract 854 from 136 you get 722....
8-1=7
5-3=2
6-4=2
722
Here is a pair example:
Look at Nov. 8 and 9.......if you subtract 905 minus 303 you get 602......a a pair on Nov. 11 mid
There are many many more examples, but I'm at work and don't have the time.
Do a back tests in your state.
