Performance & calibration
At OneTwentySeven, we publish win probabilities for every ATP Tour main-draw match, predicted by our proprietary models.
Our models are trained on decades of tour results and are updated constantly to capture the latest results.
We judge quality in two ways: how often is the model correct, and when we make a % prediction, how accurately does the % value we predict actually reflect real chance.
