Home court, dissected: a thin, mostly-shooting advantage

Pooled over 74,450 player-games, the home advantage at the box-score grain is small and lives mostly in shooting: home teams shoot 47.479% from the field versus 46.833% on the road (+0.647 points) and 36.632% versus 35.867% from three (+0.765 points), while the typical player's home-minus-away scoring gap is just +0.04 points per game.

What it means

Breaking home court into its statistical parts shows it is not a scoring explosion -- it is a sliver of extra shooting accuracy (field goal, three, and free-throw percentages all tick up a fraction of a point at home) plus tiny bumps in assists and blocks. The per-player point distribution is nearly centered on zero, meaning 'home cooking' is a faint, league-wide tilt rather than a big individual boost for most players.

Caveats & confounds

DESCRIPTIVE_ONLY. Known data issue: diacritic-split player_ids (an upstream name-join bug) can fragment one player across two ids, unfixed here; floors require 15 player-games per side.
