North Korean gymnast Ri Se-gwang scored 15.633 in the men's vault final at the 2016 Rio Olympics -- the highest vault score in Olympic history -- earning the gold medal. His routine, now officially named the "Ri Se-gwang vault," involves a front handspring onto the table followed by a triple twist. Vault outcomes are decided in mere seconds, where a margin of 0.001 points can determine the gold medal. It also stands as a rare Olympic gold for North Korean gymnastics.
