For the 11/02/2021 Evening result 5185 these were the filters my software indicated to play.
Key Digits: 5 😃
Digits Position 1: 1, 2, 5, 7 😃
Digits Position 2: 1, 2, 4, 7, 9 😃
Digits Position 3: 3, 5, 6, 7
Digits Position 4: 0, 2, 3, 6, 7
Last Digit Sums: 1, 2, 4, 5, 6, 7, 9 😃
Got 4 of 6. It's a start. Those 6 filters reduced to 125 combos.
Synopsis
Key Digits: 5 reduced combos from 10,000 to 3439
Digits Position 1: 1, 2, 5, 7 reduced combos from 3439 to 1813
Digits Position 2: 1, 2, 4, 7, 9 reduced combos from 1813 to 785
Digits Position 3: 3, 5, 6, 7 reduced combos from 785 to 395
Digits Position 4: 0, 2, 3, 6, 7 reduced combos from 395 to 175
Last Digit Sums: 1, 2, 4, 5, 6, 7, 9 reduced combos from 175 to 125
If I removed the two filters that I missed I would have 550 combos
If I would have just played Doubles it would reduce to 202 combos
I think if you are only going to filter by digits a good formula would be:
- Select 5 digits for each position this will reduce combos to 625 since this is similar to H/L or E/O pattern.
- Select 2 key digits (any one or both digits in the result)
- Select 2 digits to exclude (both digits must not be in result)
- Select 2 lowest winning digits (one of the digits is the lowest winning digit in the result)
- That should get you to under 100 combos. To reduce further select either Singles or Doubles since they cover 93% of the combos.
Anyway those are my thoughts.
Good Luck !!!
