women's figure skating is now scored
The judges' subjective points on a 6.0 scale are no longer used to score Olympic figure skating.
A 2002 Olympic figure skating controversy involving score-fixing claims upended the sport and led to a scoring system that rewards stamina and strenuous athletic performances.
This time, both die-hard and casual skaters are divided.
On December 25, Kamila Valieva, 15, supplied a test sample that later tested positive for the prohibited drug trimetazidine.
Trimetazidine can boost stamina and "help your heart perform more efficiently," according to Dr. Elizabeth Murray of the University of Rochester Medical Center.
The WADA-accredited Swedish lab revealed the adverse result on February 8, a day after Valieva and her Russian Olympic Committee teammates won gold in the team competition.
An Olympic official said Valieva blamed the positive test on a pharmaceutical mix-up.
It is "100% certain" that she is innocent, according to her coach, Eteri Tutberidze.
So Valieva could compete in the Olympic women's singles figure skating event.
The International Judging System (IJS) replaced the subjective "6.0" scoring system in 2004.
Women's figure skating has two routines: the short programme (2 minutes 40 seconds) and the free skate (4 minutes).
The current scoring system gives a 10% advantage to leaps done in the second part of the free skate because they are harder to do on fatigued legs.
This was exploited by 2018 Olympic champion Alina Zagitova, who was also coached by Tutberidze.
President Vladimir Putin congratulated the 15-year-old Russian gold medalist.
Critics said Zagitova's programme lacked beauty and relied too heavily on jumps squeezed into the second half to maximise points.
