Combined Filters ATrax Alt Sums Pick 4 The ATrax Alt Sums (ATX-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.
ATrax (ATX), for Alternate or Alternative Tracking, has to be seen an improvement of the VTracs (VTX), as it combines digits logically rather than by a simple adding of 5 to the digit. Since the conversions do not have to be done by hand any longer, other combinations can be done with simple tools online rather than with pencil and paper. 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 ATrax Alt Sums filter for a Pick 4 number here an example step by step.
Part I: Pick 4 ATrax Alt Sums Conversion Step 1: Divide 9443 into separate digits: 9443 => 9 4 4 3 Step 2: Convert each digit to filter: 9 = 2 4 = 0 4 = 0 3 = 1 Step 3: Combine the filters to a string: 2 0 0 1 = 2001
Part II: Pick 4 ATrax Alt Sums Conversion Step 1: Divide the 2001 into separate digits: 2001 => 2 0 0 1 Step 2: Sort the digits from highest to lowest: 2 0 0 1 => 2 1 0 0 Step 3: Subtract and add the digits alternately: 2 - 1 + 0 - 0 = 1
