The Gap Distribution Chart is a lottery strategy chart in Advantage Plus. 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).
