Summaries describe the filtered rows with equal row weight. Row counts are not independent game or event counts.

Reference population: All published groups. 3 rows published.

Text search does not change this reference population.

Availability describes published values only. It does not establish data quality or independent game counts, and measurement windows can differ.

01 / Interpretation

What this measures

Positive values mean the recorded recent-window rate is higher; negative values mean it is lower. Read both overlapping-window operands beside the difference.

02 / Calculation

displayed difference (pp) = 100 * (surface win rate for matches on or after 2023-01-01 - source-career surface win rate documented as 2015-2025); stored value remains the unscaled fraction

Use the table to inspect available fields and the source JSON to trace the formula inputs. CSV percentage values are stored as fractions.

03 / Population & limits

3 ATP players with both published grass rates; each operand independently clears grass_n>=30. This analysis includes ATP entries only.

Recent matches are a subset of the source-career corpus, not an independent period. Exact match counts, opponent strength, age, tournament mix, and player-specific latest match dates are not published; source as-of is the claim-computation timestamp. Unknown and carpet surfaces are excluded, while retirements remain decided matches under the source winner field. Only 3 players qualify, so grass comparisons are especially sparse. These historical differences do not establish persistence or forecast performance.
