What is the ELO Rating System?
ELO is a world-class skill rating system designed to measure a player's true performance. It doesn't simply count wins and losses — it considers who you played and how expected the result was.
- Beat a stronger opponent → earn more points
- Beat a weaker opponent → earn fewer points
- Lose to a stronger opponent → lose very few points
- Lose to a weaker opponent → lose more points
ELO is trusted because it is:
- Transparent: based on math, not opinion
- Objective: no manual ranking or arbitrary scoring
- Self-correcting: unexpected results shift the leaderboard quickly
- Universal: used in global competitive systems since the 1960s
- CourtMaster brings that same fairness to your tennis club.
How Your Rating Changes
A simple example to show how ELO works:
- Player A (1200) beats Player B (1450) → +25
- Player A loses to Player B → -3
- Player C (1100) beats Player A (1200) → +10
- Player C loses to Player A → -8
Every match matters — but not all matches matter equally.
You rise by proving yourself against strong opponents.
