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.

What stands out
- Dominant on the two faster surfaces: grass_wr_career 0.8592 and hard_wr_career 0.8543.
- Clay is the relative soft spot: clay_wr_career 0.7179, a clay-minus-hard gap of -0.1363.
- Recent-form fields fall below the sample floor and show n/a -- the card is partial (5 of 10 metrics).
Descriptive career surface win rates as of the corpus end, not a prediction and not a causal claim. Per-surface floors apply (hard/clay/grass n>=30); metrics below floor show n/a rather than a fabricated value, and nothing here adjusts for era, opponent quality, or draw.
