Combined Filters VZero Levels Pick 4 The VZero Levels (VTZ-LVL) 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. The Levels filter is a so called "math filter". Math filters are created through calculations. This filter provides a way to determine the relative "level" (height) of each digit in relation to the others, the lowest digit of a number always being 1. To show you how to calculate the VZero Levels filter for a Pick 4 number here an example step by step.
Part I: Pick 4 VZero Levels Conversion Step 1: Divide 7965 into separate digits: 7965 => 7 9 6 5 Step 2: Convert each digit to filter: 7 = 2 9 = 4 6 = 1 5 = 0 Step 3: Combine the filters to a string: 2 4 1 0 = 2410
Part II: Pick 4 VZero Levels Conversion Step 1: Divide the number into separate digits: 2410 => 2 4 1 0 Step 2: Select the unique digits and order from lowest to highest: 2 4 1 0 => 0 1 2 4 Step 3: Assign a level to each digit starting with 1: 0 => 1 1 => 2 2 => 3 4 => 4 Step 4: Convert the number using the table above: 2 4 1 0 => 3 4 2 1 Step 5: Combine the filters to a string: 3 4 2 1 = 3421
