A good tool I found was to use the last draw's individual numbers in your state and look for combos vertically in your recent past winning numbers. Since about 70% of the time, at least one of the numbers in the last draw are repeated in the next draw, and since a lot of winning combos can be found by looking vertically in your recent past winning numbers, it would only make sense to use this for either real play of all the combos associated with the number, or as a comparison tool.
For example, June 5 mid was 727. The draw before was 667 on June 4 eve. We use the individual numbers in 667....6 and 7 to look back vertically in the recent past for possible combos. Of course we'd have to do all the 6's also ....
And if you look, you can see that you can narrow down which of the many 7's in the recent past to use by employing my "4 to 6 day rule" system. The 772 falls within the range of 4 to 6 days back. So maybe only play the 7's that are within the 4 to 6 day window...
For even more confirmation, you can use the "30 day back" system. Look back 30 days from the day you're playing on and look for any pairs with 7's. 30 days back from June 5 is May 5.
May 5 mid- 454 eve-237...............Maybe only play the combos that appear in the vertical that have a 2 and 7......
Example: Florida,
Mid Eve
May 29 528 143
May 30 477 735----------6 days back
May 31 957 063----------5 days back
June 1 742 943----------4 days back
June 2 563 456
June 3 523 173
June 4 384 667
June 5 727 987
June 6 410 899
