The Gap Distribution Chart is a lottery strategy chart in Advantage Plus (Option L). The purpose of this chart is to show an analysis of the space between the numbers drawn when arranged in increasing number order. A gap of zero between two numbers indicates successive numbers, EX 01-02 or 49-50. Note: This is referring to the number of missing numbers between two numbers (in this case 0) and not the difference between two numbers (which would be 1 in this case). A gap of 5 would represent numbers with a difference of 6, ex: 05-11 (the missing numbers are 6,7,8,9 and 10).
