HOW ARM RATING WORKS

The Alley Roller Mastery (ARM) rating system evaluates skeeball performance based on 5-game sessions. Ratings range from 7.0 (beginner) to 25.0+ (elite).

Your rating adjusts based on session performance compared to expectations for your current level. New players see larger rating changes as the system learns their skill level.

Each game is scored 0-900 points, making the maximum session total 4500 points. Consistent performance around 1800-2000 total typically maintains a 10-12 ARM rating.
