Season ELO trajectory

One point per match: the player's ELO rating after that match, matches in round order. Ratings are season-scoped: every January the engine re-seeds each player from WTA entry points, then updates after every result. That is why trajectories are shown one season at a time. Hover a point for the match behind it.

Serve predictions: how close do we get on Qinwen Zheng?

2025 · out-of-sample backtest Aces per match: 5.0 actual vs 6.0 projected
2.73 our average miss per match
2.31 baseline average miss (last five matches)
-18% accuracy edge over the baseline

Comparison covers 27 of the 32 aces projections we made in 2025. A match needs five earlier matches on record before the baseline exists.

The baseline predicts a player's aces as the average of their last five matches. Our model beats it when its projections land closer to what actually happened. Both numbers are the average miss per match, so lower is better, and both are for the selected season only.

An upset = our model's favorite losing. "Upsets" compares how many actually happened in Qinwen Zheng's matches with how many the model expected for that exact schedule.
