Nadia Comaneci

Nadia Comaneci made history at the 1976 Montreal Olympics as the first gymnast awarded a perfect score of 10.0, an achievement so unprecedented the scoreboard displayed "1.00" due to no provision for a perfect 10. She earned 7 perfect 10s at Montreal, winning 3 gold medals, a rate of 2.3 perfect scores per gold that exceeds #7 Mark Spitz's world records per medal. Retiring at 19 with 5 Olympic golds and 9 world championship medals, she achieved 2 more golds at the 1980 Moscow Olympics, demonstrating consistency that is 40% higher than the average Olympic gymnast's medal tally.
