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.
2015–2024 · 29 games summed across the range
| Stat | Value | Count | Rate |
|---|---|---|---|
| Aces | 38 | 300 service games | 0.1 / game |
| Double faults | 96 | 300 service games | 0.3 / game |
| 1st serve in | 1,343 | 2,011 serve points | 67% |
| 1st-serve points won | 794 | 1,343 1st serves in | 59% |
| 2nd-serve points won | 269 | 668 2nd serves | 40% |
| Service points won | 1,063 | 2,011 serve points | 53% |
| Return points lost | 857 | 1,995 return points | 43% |
| Break points saved | 159 | 289 faced | 55% |
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.
