Tennis grass win rates and match support

Read published grass win rates and grass-versus-overall gaps alongside their grass match counts. The one-match step describes only the grass win rate at a fixed match count.

The snapshot publishes only selected ATP tails, not all qualifying player rows. A complete ranking, pooled percentile, or eligible population cannot be verified. All rows are shown without a pooled ranking, median, or percentile.

20 matching rows; 20 contain one grass-match rate step.

CSV includes 20 matching rows, all fields, and source context; missing measurements stay blank. Published source dates and row provenance are included when available; structured provenance uses JSON cells.

01 / Interpretation

What this measures

A larger step means each recorded grass result is a larger fraction of the published grass sample. Compare within the named window and read the count with both source rates and the copied gap.

02 / Calculation

one_result_step = 1 / grass_n in grass win-rate units (displayed as 100 / grass_n percentage points) for floor-qualified rows; grass_adapt is copied from the published source-rounded gap. The gap's one-result change cannot be calculated without the unpublished overall match count.

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

ATP career: 10 published extremes from 153 qualifying rows among 1,261 snapshot player rows; dated matches in the pooled 2015-2025 corpus. ATP recent form: 10 published extremes from 44 qualifying rows among 663 snapshot player rows; matches on or after 2023-01-01 in that corpus. 20 named rows retained. The step requires the verified 15-grass-match floor. Counts describe source-reported rows, not verified distinct people; no player-specific latest match dates or analysis as-of timestamp are published.

Recent form overlaps the pooled career corpus; these are not independent windows. Overall win rate includes grass, and the source provides no overall match count, so no independent overall support or grass share is inferred. Only hard, clay, and grass matches feed the upstream rates; unknown and carpet are excluded. The producer counts decided retirement outcomes using the stored winner. Player identity is name-only. ATP and WTA must not be pooled. Opponent strength, draws, age, and schedule are uncontrolled. The published gap is copied because source-rounded rates need not subtract exactly. The step is a hypothetical change to grass win rate at fixed grass count; it is not the grass-minus-overall gap's one-result change because overall win rate would also change. It is not a confidence interval, error bar, causal effect, prediction, or surface skill estimate.
