12年羽毛球单打比赛采用的是几分制？

2012年羽毛球单打比赛采用的是21分制。这意味着在一局比赛中， whoever first reaches 21 points wins the game, and it is a best of three games format. This scoring system has been the standard for many years now, replacing the old 15-point rally point system that was used in men's singles and the 11-point system in some other contexts previously.
