Stan Wawrinka (ATP)
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
- Career hard is a touch above clay (hard_wr_career 0.618, clay_wr_career 0.5804).
- Recent form is down across the board: hard_wr_recent 0.434, clay_wr_recent 0.4167.
- Grass is the weak surface -- grass_adapt_career -0.1153, with career grass win rate below the floor (n/a).
Descriptive career and recent-form surface win rates as of the corpus end, not a prediction and not a causal claim. Recent-form figures can reflect thin post-floor samples; per-surface floors apply (n>=30) and below-floor metrics show n/a. No adjustment for era, opponent quality, or draw.
