PLAY TIP
IT'S clear that for some PAIRSUMS a color should NOT be considered as one of the OVERDUE colors because they do not hit often at all. THE KEY is to isolate SINGLE and DOUBLE numbers and it will disclose the colors not to ever play in a pairsum.

Some pairsum colors don't hit often so those are the ones that should NOT be considered or you could be waiting many draws before they hit. The best method is to (1) take the colors that hit often, (2) look at those overdue colors and (3) use the binary filter to remove the color(s) that don't hit often. You will then be able to see which color that hits often is most overdue.
In this example, you can see the RED highlighted colors/numbers are the ones that do NOT hit often in a pairsum. Thus, REMOVE those binary colors in the chart filter and view which of the remaining colors are most overdue. FOR EXAMPLE in pairsum 7/2,3, PURPLE should be REMOVED and only GREEN,BLUE,YELLOW considered.
