The Equalizer? Handicap System
The uniqueness of The Equalizer? handicap system is that it brings out the best in both the novice/beginning player and the expert should they compete in a match. With The Equalizer?, it's feasible for a beginner to have a nearly equal chance in a match against a more highly skilled player. The Equalizer? aids the lesser skilled player by dictating mathematically that he/she needs to win fewer games or points than his opponent to win the match. (In golf and bowling, you give or get strokes or pins.)
In an APA League, you give or get games in the 8-Ball format and you give or get points in the 9-Ball format. How many games or points you give or get is determined by comparing your skill level to your opponent's skill level. A higher skilled player must give games or points to a lower-skilled player, thus evening the match.

1. HOW HANDICAPS ARE DETERMINED
Your Local League Office calculates and reports skill levels to the teams on a regular basis. Your skill level determines how many games you have to earn to win your match. Skill levels are maintained, calculated and updated by the Local League Office. The process includes a number of factors including the application of specific mathematical formulas to the data on the weekly scoresheets, win/loss records, Higher Level Tournament performance,
qualitative judgment by Handicap Advisory Committees, and other considerations. You are asked to refrain from attempting to keep your own records as it is generally a disruptive practice. The APA appreciates your cooperation with this policy.
