Rounds are the round each match was played in, not a ladder: a player enters a 32-draw straight in R32, and team events (United Cup, Davis Cup) are not played through a draw at all — those have their own row. Ranking bands use the opponent's ranking on match day and are cumulative: top 100 includes top 10.
Surface record by season
Each cell is one season on one surface: the number is wins–losses, the colour is the win rate. Carpet is counted as indoor hard.

Season statistics
Each stat is stored as a value–count pair, so seasons can be added together and the rate is always value ÷ count.
2018–2025 · 2 games summed across the range
| Stat | Value | Count | Rate |
|---|---|---|---|
| Aces | 0 | 19.5 service games | 0.0 / game |
| Double faults | 6 | 19.5 service games | 0.3 / game |
| 1st serve in | 113 | 157 serve points | 72% |
| 1st-serve points won | 60 | 113 1st serves in | 53% |
| 2nd-serve points won | 20 | 44 2nd serves | 45% |
| Service points won | 80 | 157 serve points | 51% |
| Return points lost | 42 | 123 return points | 34% |
| Break points saved | 9 | 18 faced | 50% |
Value is what happened (aces hit, points won), count is how often it could (service games, points played). Adding seasons adds both — the rate is never averaged from percentages.
