01 / Interpretation

What this measures

Sort a column to inspect the published measurements. Unavailable values remain unavailable, and a higher value is not a quality judgement.

02 / Calculation

Displayed values restate published scalar key_numbers fields. The field definitions preserve each published unit: already-percent values are normalized for percent display, and published fractions are shown as percentages.

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

19 published MLB pitch types rows and 5 scalar measurement fields.

all 19 pitch_type codes in the 2025 pull included, no exclusion (missing pitch_type kept as 'UNK'); smallest category n=7 (SC) -- small-n cards carry high sampling noise, shown for completeness not comparison. no per-pitch swing/miss field in this pull (no `description` column; `type` merges called+swinging+foul into one S bucket, `des` only fires on PA-ending pitches) -- outcome mix (ball/strike/in-play) substitutes
