12年羽毛球单打比赛采用的是几分制?
The current standard scoring rule in badminton is quite specific. If the score reaches 20-20, a player needs to lead by 2 points to win the game. However, if the score goes up to 29-29, the next point wins the game, meaning leading by just 1 point at that stage is sufficient to take the set. This ensures games don't go on indefinitely.
