Historical measurements from this snapshot.
ATP surface windows: source corpus documented as 2015-2025; career uses all dated corpus matches, while recent starts 2023-01-01 and overlaps the corpus. Published floors apply independently for each metric and window. Exact player match counts and latest match dates are not published. The as-of date records claim computation, not a match cutoff.
