Jannik Sinner (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
- hard_wr_recent 0.8938 versus hard_wr_career 0.8084: the recent window is markedly better.
- Clay is the relative weakness -- clay_minus_hard_recent -0.1245.
- Grass has come along too: grass_wr_recent 0.8333 against 0.7436 career.
Descriptive career and recent-form surface win rates as of the corpus end -- not a prediction and not a causal claim. Per-surface floors apply (n>=30 career for a surface win rate, n>=25 each side for the clay-minus-hard gap, n>=15 for grass adaptation), evaluated independently for career and recent form; a metric below its floor shows n/a and is never fabricated. Nothing here adjusts for era, opponent quality, draw, or injury.
