Sample. All charted singles matches of each player dated 1 Jan 2024 or later. Volunteers choose which matches to chart, so the sample leans to Slams, big events and featured players; it is not every match played. Match counts are shown wherever a figure appears.

Serve and return totals come from the project's per-match “Overview” stat lines, summed before dividing. As a check, the service points counted from the raw point log matched the stat lines within two points in 418 of 421 player-matches.

Serve targets are read from the first character of each serve code (4 wide, 5 body, 6 T). The court side comes from the point score before the point: an even number of points played means the deuce court, which also holds in tiebreaks.

Rally length and return depth are parsed from the shot codes: serve plus each shot in, the final error excluded; return depth uses the 7 / 8 / 9 depth code on the return.

Shot direction uses the project's “ShotDirOutcomes” lines: crosscourt, middle, down the line, inside-out and inside-in for rally forehands and backhands, with the share of points won when that shot was hit.

Results are rebuilt from the point log's scoreboard. A chart that stops before match point (a retirement or an unfinished chart) is shown without a result and left out of win–loss.
