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 Nikola Bartunkova?

2025 · out-of-sample backtest Aces per match: 4.2 actual vs 2.8 projected
- our average miss per match
- baseline average miss (last five matches)
- accuracy edge over the baseline

Not enough matches with a baseline in 2025 for a fair comparison. The chart still shows every match we projected.

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.
