A school in parentheses: the play-by-play credits this set to a player on the other team, as the feed wrote it. “As written”: a name the feed gives that isn't in either box score.

Setter not recorded: the play-by-play names no setter. Most are unassisted kills (setter dumps, overpasses); a setter is filled in only where the box score's assists prove who it was.
