Series results and records count playoff finals more than 6 hours old; fresher finals are listed as provisional. Regular-season games are a separate scope, never added in.

A round is named only when the game id gives it; otherwise the game reads Playoffs.

Sport Data Service does not hold NBA play-in games, so none is listed here or counted anywhere.
