Performance & calibration
At OneTwentySeven, we publish win probabilities for every ATP Tour main-draw match, predicted by our proprietary models.

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.
