Combined Filters Neighbors Sums Pick 4 The Neighbors Sums (NB-SUM) 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 Sums filter is a so called "math filter". Math filters are created through calculations. You get the sum of a number by adding up the digits within that number. To show you how to calculate the Neighbors Sums filter for a Pick 4 number here an example step by step.
Part I: Pick 4 Neighbors Sums Conversion Step 1: Divide 2042 into separate digits: 2042 => 2 0 4 2 Step 2: Convert each digit to filter: 2 = 2 0 = 1 4 = 3 2 = 2 Step 3: Combine the filters to a string: 2 1 3 2 = 2132
Part II: Pick 4 Neighbors Sums Conversion Step 1: Divide the 2132 into separate digits: 2132 => 2 1 3 2 Step 2: Add up the digits: 2 + 1 + 3 + 2 = 8
