Just an update to let you know how this strategy is working for me...
I'm getting an average of 7 hits a week or 50% of the draws hitting off these workouts -- minimum hits was 6 and maximum was 11/14!
What I do is make the rundown on Sunday night's number (or the closest non-double number). I found that this doesn't work as well if all the numbers are even or odd, so I will add one to make sure that doesn't happen. Eg 589 divided by mirror 034 = 17.3 so add one to make 174.
Then I take all the pairs from the workout and mash them together so that two pairs make a 3 digit combo, eg. 03 and 08 are combined to make 038.
This makes about 30 combos which I filter before each game by eliminating combos with same root sum as last game, eliminating combos with numbers that I don't think will hit, etc.
I am very happy with this method!
