There are 14 ranges so the optimal range from a statistical aspect would be the 7th set of Sum Total Pairs. The last set above (07 thru 20) IS the optimal range from a statistical aspect. The ST's are color-coded to show the sister sum pairs. The sister sum pairs above the optimal range are also a way to reduce the number of probable numbers to play. Remember they MUST be eliminated or added in pairs.
The optimal range is still a lot of numbers. I will explain now how to reduce these further.
Begin with the last draw for your state and begin eliminating just the optimal sums above. After you eliminate one of the optimal sums, eliminate it's sister sum on the other side. Continue doing this until you have just a few pairs left.
Those left are the sister sum pairs that are both optimal and overdue to hit.
With so much pressure on Root sum #3
And it can still come.
In Theory:
The sum totals 13 and 14 have equal probability. I don't have the chart handy so I'm winging it. If ST 13 is overdue then ST 14 is equally probable to fall. I haven't done any research with drawfiles but it stands to reason that if you eliminate ST's going back in the draw history until you find a ST Pair that has not hit then those two ST's would be the numbers to filter for.
Just my two cents but it should work.

Please post findings and comments
LOOKING AT ROOT SUM#3=12 sum
Equivalent to sum 12* its sister sum
is 15* sum ,which George says stands
an equal chance.
