Model v5 · Updated 23 Sep 2026

Our track record

Every forecast checked against the final 90-minute result, by league, competition and season. Nothing is hand-picked: every graded match counts.

The backtest runs model v5 over past seasons from Jun 2008 to Sep 2026. For every match it only uses information that existed before kickoff, exactly as if the forecast had been published that day. The model was tuned on matches from January 2025 to April 2026; every other month is an out-of-sample test.

Hit rate counts the outcome we marked as most likely. Brier score and log loss grade the full probabilities, so a confident miss costs more than a cautious one.

Paler bars have fewer than 100 matches and move a lot by chance. The earliest seasons have few matches and little history for the model to learn from, so they read lower.

Do the percentages mean what they say?

Each dot groups home, draw and away probabilities of similar size. Dots close to the diagonal mean that when we say 60%, it happens about 60% of the time.

Reading the numbers

How we measure accuracy

Hit rate
How often the outcome we marked as most likely happened. Simple, but it ignores how confident the forecast was.
Brier score
The squared gap between our probabilities and what happened. 0 is perfect; for match results, spreading a third on each outcome scores 0.667.
Log loss
Punishes confident mistakes harder than the Brier score. Lower is better.
Backtest
The current model run over past matches with only the information available before each kickoff. It shows how the model behaves across many seasons, but it is a simulation, not a record of published forecasts.
Published forecasts
Forecasts we actually showed, stored with a timestamp before kickoff and never edited afterwards.
Result used
The score after 90 minutes plus stoppage time. Extra time and penalties do not count.
Forecast archive → Methodology →

Forecasts are probabilities, not certainties. Past accuracy does not guarantee future results.
