Performance

Ballr checks every five minutes and saves the first available forecast within 24 hours of kickoff, while results data is fresh. A saved prediction is never overwritten. Recording begins when this feature is deployed; older matches are not retroactively added.

The Brier score measures all three probabilities. Lower is better; equal one-third probabilities score 0.667. The baseline uses historical home/draw/away frequencies available to Ballr at the time of each prediction.

Postponed matches with changed kickoff times or teams are excluded. This page evaluates the win/draw/win model only, not exact scorelines or betting returns. Small samples do not establish predictive skill.
