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 0568 into separate digits: 0568 => 0 5 6 8 Step 2: Convert each digit to filter: 0 = 0 5 = 0 6 = 1 8 = 3 Step 3: Combine the filters to a string: 0 0 1 3 = 0013
Part II: Pick 4 VZero Levels Conversion Step 1: Divide the number into separate digits: 0013 => 0 0 1 3 Step 2: Select the unique digits and order from lowest to highest: 0 0 1 3 => 0 1 3 Step 3: Assign a level to each digit starting with 1: 0 => 1 1 => 2 3 => 3 Step 4: Convert the number using the table above: 0 0 1 3 => 1 1 2 3 Step 5: Combine the filters to a string: 1 1 2 3 = 1123
