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

113 ATP players with both published hard rates; each operand independently clears hard_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. These historical differences do not establish persistence or forecast performance.
