Calibration & Methodology
Our model is calibrated weekly against actual match outcomes. If we notice a deviation in specific leagues or markets, our algorithm weights are adjusted to reflect current trends.
We use a Brier Score to measure the accuracy of our probabilistic predictions. The lower the score, the more calibrated the model is to reality. Our current rolling average Brier Score for the 2025/26 season is 0.18.
League Performance
Our highest accuracy currently resides in the Premier League and Bundesliga, where data availability is highest. We are continuously expanding our data depth for the Championship and secondary European leagues.
