What is ELO in amateur tennis
Learn how the ELO ranking system works in Argentine amateur tennis and why it's the fairest way to measure your level.
The ELO system: from Arpad to Argentine courts
The ELO rating system was created by Hungarian physicist Arpad Elo in the 1960s to rank chess players. Today it's used in sports, video games, and — thanks to iapelota — in Argentine amateur tennis.
How it works
Each player starts with a base score (typically 1500). After each match, points are redistributed between winner and loser based on the previous rating difference:
- If you beat someone with a much higher ELO, you gain many points.
- If you beat someone with a much lower ELO, you gain few.
- Losing to a better player doesn't penalize you much.
The system self-calibrates over time. The more matches you play, the more accurate your rating becomes.
Why ELO instead of just league points
Traditional league rankings reward match quantity and participation. ELO measures quality of play:
- It doesn't matter if you played 10 or 100 matches
- What matters is who you beat or lost to
- A player who consistently wins against strong opponents climbs faster
