sample floor
as of 2025-09-28
An entity earns a descriptive card only after clearing a minimum-sample floor, so rates are not read off tiny samples. The floor for this pack is pitches_faced_2025>=300 (yields 485/671 batters). launch_speed/estimated_woba_using_speedangle populated only on batted-ball rows (contact-panel n is batted balls, not pitches_faced); no swing/miss or launch_angle column in this pull, so whiff rate and a launch-angle barrel profile are not built here (same gap noted in mlb_pitch_atlas).. Entities below the floor are deliberately left off -- we do not print rates we cannot stand behind.
