Samples & availability

Only results observed as finished up to now are eligible. 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 8/12 / 4/12 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.
