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 8412 into separate digits: 8412 => 8 4 1 2 Step 2: Convert each digit to filter: 8 = 3 4 = 4 1 = 1 2 = 2 Step 3: Combine the filters to a string: 3 4 1 2 = 3412
Part II: Pick 4 VZero Distance Codes Conversion Step 1: Divide the number into separate digits: 3412 => 3 4 1 2 Step 2: Calculate the distance between each digit and the next (the last digit with the first): 3 to 4 => 1 4 to 1 => 3 1 to 2 => 1 2 to 3 => 1 Step 3: Convert distances to codes (0=E[qual], 1 & 9 = C[onsecutive], 2-8 = N[one]): 1 => C 3 => N 1 => C 1 => C Step 4: Combine the filters to a string: C N C C = CNCC
