Radical transparency

Performance & Accuracy

We publish how every model actually performs (winner accuracy, point-spread and total error, and calibration) for each sport and season. No cherry-picking, no black boxes.

We aim to be the most transparent name in sports analytics, not the loudest.

Every prediction we make is published and later scored against the real result. Calibration curves are open for every model. The numbers below are live, recomputed from our own track record, wins and misses alike.
