Combined Filters Neighbors Alt Sums Pairs The Neighbors Alt Sums (NB-AS) is a so called "combined filter", a combination of a digit and a math filter. It requires two separate parts to create the filter.
Neighbors (NB) is yet another alternative to the old VTracs (VTX). Instead of combining digits by adding 5 it selects the all even digits with the next odd digit up, 0 with 1, 2 with 3 all the way to 8 with 9. It is another efficient way to combine an odd with an even digit. The Alt Sums filter is a so called "math filter". Math filters are created through calculations. In this case starting with the highest digit of the number the digits are alternately subtracted and added to create the Alt Sums between 0 and 9. To show you how to calculate the Neighbors Alt Sums filter for a Pick 2 number here an example step by step.
Part I: Pairs Neighbors Alt Sums Conversion Step 1: Divide 86 into separate digits: 86 => 8 6 Step 2: Convert each digit to filter: 8 = 5 6 = 4 Step 3: Combine the filters to a string: 5 4 = 54
Part II: Pairs Neighbors Alt Sums Conversion Step 1: Divide the 54 into separate digits: 54 => 5 4 Step 2: Sort the digits from highest to lowest: 5 4 => 5 4 Step 3: Subtract and add the digits alternately: 5 - 4 = 1
