That makes a good point: new badminton scoring format would tempt Lee Chong Wei for 2020 Olympic Games in Tokyo
The Badminton World Federation is experimenting with an 11-point, best-of-five system, instead of the traditional 21-point, best-of-three format

Malaysia’s world number one Lee Chong Wei said a new scoring format could tempt him to extend his career to the Tokyo 2020 Olympic Games and take yet another shot at an elusive badminton gold medal.
The 33-year-old’s interest has been piqued by the Badminton World Federation’s (BWF) experiments with an 11-point, best-of-five system, instead of the traditional 21-point, best-of-three format.
Lee said Chinese fellow veteran Lin Dan, a two-time Olympic champion, may also be persuaded to play on under the new system, which is considered less physically demanding and therefore better for older players.
“Nothing is confirmed yet, but if there is indeed a change I could very well compete at the Tokyo Olympics,” Lee was quoted as saying by the The Star newspaper.
“Even Lin Dan might play on as the 11-point system would mean shorter matches...which is better for senior players like us.
