Perfect 10 refers to a score of 10.00 for a single routine in artistic gymnastics, which was once thought to be unattainable—particularly at the Olympic Games—under the code of points set by the International Gymnastics Federation (FIG). The first person to score a perfect 10 at the Olympic Games was Romanian Nadia Comăneci, at the 1976 Games in Montreal. Other women who accomplished this feat at the Olympics include Mary Lou Retton in 1984, and Daniela Silivaș and Yelena Shushunova in 1988. The first man to score a perfect 10 was Alexander Dityatin, at the 1980 Olympics in Moscow.
