What is Elo?

Elo is a method for calculating the relative skill levels of players in two-player games, such as chess. It is named after its creator Arpad Elo, a Hungarian-American physics professor.

• Elo is used to rank teams based on their performance.
• Teams gain Elo points by winning games and lose points when defeated.
• The amount of points gained or lost depends on the relative Elo ratings of the competing teams.

Elo provides a way to compare teams across different regions and track their performance over time.

Despite the simplicity of the algorithm, it is surprisingly effective as predicting outcomes.
