Definition

Elo rating

A strength score updated after every match: beat strong teams and it rises, lose to weak ones and it falls.

How it works

Borrowed from chess, Elo keeps a number per team and exchanges points after each result — the winner takes from the loser, sized by how unexpected the outcome was. Over a season it tracks true strength better than raw points.

In our model

Elo-style ratings built from historical results are refreshed per league and seed each side's expected goals; recent form and home advantage adjust from there.

FAQ

Why not just use the league table?

Tables ignore schedule strength and carry early-season noise; ratings update continuously and compare across matchups.

When are ratings least reliable?

Early in a season, after promotion/relegation and long breaks — we flag the increased uncertainty.
