4 matching rows; 2 contain clay-positive players.

CSV includes 4 matching rows, all fields, and source context; missing values stay blank.

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

Measurement availability4 / 4 fields have values

Reference population: All published groups. 4 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

A positive balance means surface-positive profiles outnumber surface-negative profiles among players who clear the stated floor.

02 / Calculation

positive share = published qualifying-player fraction above zero; balance = positive share - 0.5

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

Only cohorts with a published qualifying distribution contribute numeric rates; all four cohort rows remain visible.

Positive-share balance counts players, not matches, and does not measure the magnitude or persistence of a player's surface difference.

04 / Source & method references

References explain ingredients and prior methods. They do not validate this derived analysis or establish its originality.
