For capping purposes, a point is considered to begin immediately after the preceding goal is scored.
Finish the current point. The game is over unless it's a tie.
If the game is tied, play one more point.
If the lights go out before a game is officially over, the game will end immediately. If the disc is in the air when the lights go out and it is caught in the dark in the end zone for a score, it will count. In any other situation, the game will immediately end even if it is mid-point. If the game is tied, the game will be scored as a tie.
