Frequently asked questions

Why do some matches have no prediction?

Three cases. The match is outside the scope where the model is calibrated and measured (ATP, from Challenger to Grand Slam): it is listed with its odds, without a prediction. An alert from our engines is active on this match: the prediction is reserved for subscribers until the market closes, then becomes public again. Or the match profile could not be computed.

How reliable are these predictions?

Version 1.1.0 of the model picks the right winner in 67.39% of cases on 59,960 ATP matches since 2021, against 67.07% for the bookmaker's favourite on the same matches. The figure alone says nothing: each day's record is published and verifiable.

Is a prediction betting advice?

No. The model's favourite wins most of the time, but a bet only has value when the odds exceed 1 divided by the probability. Our paid alerts exist only in that case, on about two matches in a hundred.
