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.
