The sweet spot for the Freq Range and Skip Range filters are 3-7. In addition another filter that has a high acurracy is my Sums Repeat filter set to 0. What this means is that the previous sum, root sum, and short sum will not repeat for the current draw. This has an accuracy of about 85%.
So if you always play the above 3 filters you will be accurate 0.9 * 0.9 * 0.85 = 0.69. So you would be accurate 69% of the time. These 3 filters eliminate between 300-400 straight combos. So 69% of the time you would be playing between a 600-700 number pick3 game.
The killer filter to play with these 3 filters would be my OELHIO repeat filter. Its calculated as follows:
If the Odd/Even count repeats from previous draw this counts as 1.
If the Low/High count repeats from previous draw this counts as 1.
If the Inner/Outer count repeats from previous draw this counts as 1.
So the filter can range between 0 and 3. When you set this filter to 3 then it reduces the matrix to between 1 and 10 box combos. Of course to have the Odd/Even/Low/High/Inner/Outer repeat is a rare occurence so you need a trigger. Here's a picture of one winner from the Georgia Combined Pick3 draws.
OELHIO example
Over the last 100 draws in Georgia combined an OELHIO filter of 3 occured 5 times of which we would have won 4 times. 1 time the skip range filter filtered the winner out. That's okay we only expect the other 3 filters to be correct 69% of the time.
The winners were on these dates:
07/29/2013 449 Straight Combos - 27 Box Combos - 5 Win $160 - Box Play
07/28/2013 655 Straight Combos - 9 Box Combos - 2 Win $160 - Box Play
07/01/2013 067 Straight Combos - 30 Box Combos - 5 Win $ 80 - Box Play
06/25/2013 561 Straight Combos - 33 Box Combos - 6 Win $ 80 - Box Play
06/22/2013 007 Straight Combos - 45 Box Combos - 8 Win $ 0 - Winner got filtered out.
So for a cost $26 you could have won $480. Of course the key is to know when to start playing for OELHIO repeat to have 3.
If you can just predict the OELHIO Repeat filter to the exact value of either 0, 1, 2, or 3 then this play will always yield a profitable box play as long as the other 3 filters hit also. The exact play of 2, 3 for OELHIO yields the lowest box play combos.
