Nadia Comaneci

Nadia Comaneci became the first gymnast to score a perfect 10.0 at the 1976 Montreal Olympics, and she achieved nine such perfect scores in that single event, winning three gold medals. Her iconic routine on the uneven bars, where the scoreboard displayed 1.00 due to its inability to show 10.0, remains the defining image of Olympic gymnastics. This feat is faster than the average of all gymnastics routines from her era by 2.0 points on the difficulty scale. She outperforms #6 Florence Griffith-Joyner in terms of sustained perfect execution across multiple disciplines, as Griffith-Joyner's records are single-event focused. Comaneci's 14-year-old performance set a benchmark for technical perfection that inspired generations.
