Court distance is measured on court, not travel between venues. Distance and speed require three measured matches per player; their averages use measured matches only.
Separate annual scope. Only profiles observed before this match are included; these records do not change with the recent-match filter. Recorded years may be incomplete.

Only results observed as finished before match start are eligible. The current match, later results and unverified historical versions are excluded. Some historical observations were not recorded before this match; they are not reconstructed from later totals. Partial windows are shown honestly, without filling from another court or older matches.
Court is known for 2/2 / 2/14 selected matches. Indoor means a verified indoor court; unknown is not outdoor. Retirement outcomes remain in form, but partial-match performance is excluded. Rates use recorded point totals when complete, otherwise mean match rates. A 0/0 rate is undefined, not zero.
Travel distance, height, handedness and weekly ranking history: not available in this comparison. Values without a pre-start observation remain missing; we do not substitute current career or season totals.
