ELO Points System

Dynamic rankings that reflect your real playing level

What are ELO points?

The ELO system is a mathematical method for calculating the relative skill levels of players in competitive games. Each player has a numerical score that represents their current skill level.

Dynamic

Your score changes after each match

Fair

Considers your opponent's strength

Accurate

Reflects your real playing level

Unlike traditional point systems where you earn the same points for each victory, the ELO system considers your opponent's quality. Defeating a stronger player gives you more points than defeating a weaker one.

History of the ELO System

The ELO system was created by Arpad Elo, a Hungarian-American physics professor, originally to rank chess players. The World Chess Federation (FIDE) adopted it in 1970.

We implement it in our league

Since then, the system has been adapted for many sports and competitive games, including tennis, football, video games, and now our amateur tennis league.

Why do we use ELO?

We chose the ELO system for our league because we want every match to be exciting and fair. Traditional league systems can create unbalanced pairings.

Why is it perfect for us?

Amateur league with different levels

We have players from beginners to advanced. ELO ensures everyone has competitive matches.

Flexible Swiss system

Our Swiss format benefits from ELO to create optimal pairings each round.

Continuous motivation

There's always something to play for. Even if you can't win the league, you can improve your ELO.

Visible progress

Players can see their improvement over time, not just in one season.

At Tenis del Parque, you'll start with a base ELO according to your declared level: Beginner (1100), Intermediate (1200), or Advanced (1300). After each match, your ELO will adjust based on the result and your opponent's strength.

How ELO works in our league

Here's how we calculate ELO changes after each match:

Practical example

Before the match
Ana1300
Carlos1150
Result

Ana wins 6-3, 6-4

Calculation
  • Ana has 100 more ELO points
  • The system expects Ana to win ~64% of the time
  • Ana wins: +12 points (1262)
  • Carlos loses: -12 points (1138)
  • If Carlos had won: +20/-20 points

K Factor

We use a K factor of 32 to allow significant but not drastic changes. This means the maximum you can gain or lose in a match is 32 points.

Benefits of the ELO System

The ELO system offers multiple advantages for players and organizers:

Balanced competition

Pairings are fairer by considering each player's real level

Continuous motivation

Every match matters, maintaining interest throughout the season

Merit recognition

Beating stronger players is rewarded with more points

Total transparency

The system is mathematical and objective, without subjective interpretations

ELO Categories in our league

Although we have three registration levels, your ELO can vary freely within any range:

Your initial ELO is just a starting point. After a few matches, your score will reflect your real playing level, regardless of the category you registered in.
