Combined Filters VZero Distance Codes Pick 4 The VZero Distance Codes (VTZ-DSC) is a so called "combined filter", a combination of a digit and a math filter. It requires two separate parts to create the filter.
VZero (VTZ) is a different representation of the VTracs (VTX) concept with the difference that the digits start with 0 rather than 1. That simplifies the conversion drastically as the first five digits (0, 1, 2, 3 and 4) are the same in both number and VZero conversion.
To show you how to calculate the VZero Distance Codes filter for a Pick 4 number here an example step by step.
Part I: Pick 4 VZero Distance Codes Conversion Step 1: Divide 4478 into separate digits: 4478 => 4 4 7 8 Step 2: Convert each digit to filter: 4 = 4 4 = 4 7 = 2 8 = 3 Step 3: Combine the filters to a string: 4 4 2 3 = 4423
Part II: Pick 4 VZero Distance Codes Conversion Step 1: Divide the number into separate digits: 4423 => 4 4 2 3 Step 2: Calculate the distance between each digit and the next (the last digit with the first): 4 to 4 => 0 4 to 2 => 2 2 to 3 => 1 3 to 4 => 1 Step 3: Convert distances to codes (0=E[qual], 1 & 9 = C[onsecutive], 2-8 = N[one]): 0 => E 2 => N 1 => C 1 => C Step 4: Combine the filters to a string: E N C C = ENCC
