Frequently asked questions

What time are the day's tennis predictions published?
Every morning, before the first match of the day. The model computes a win probability for every scheduled ATP, WTA and Challenger match, then locks it: it is never modified afterwards, even if the odds move or the match goes live.
What do these pages show before the match?
The model's favourite for every match, before it starts. The win probability and likely score are for members, free during the beta. Once the match is over, everything is published here with the result, so anyone can check what the model announced.
How is the displayed accuracy calculated?
It is the model's accuracy measured in testing: on ATP, WTA and Challenger matches played in 2025 and 2026, which it never saw during training, the share of matches the predicted player won. A cancelled match or a walkover is not counted. Every prediction published here is then checked on its match page.
