Uchang Son (손우창) has been competing for 10 years. His best event is the 3×3 one-handed: a personal-best single of 15.45, set at Korean Championship 2017, puts him in the top 9.1% of the 73,695 people who have ever been ranked in the event, and 126th in Republic of Korea. Until May 2008, no official 3×3 one-handed solve in the world had been that fast. Across 6 competitions since December 2016, he has put 94 official solves on the record across seven events. Solve to solve, his 3×3 times vary about 12% around a typical one, an early reading from 7 counted rounds. His 3×3 best has come down from 18.55 in December 2016 to 11.02, a 41% improvement. Uchang has entered six competitions, more competitions than 86% of everyone who has ever competed.

Reading this page: a single is one solve's time · an average is the middle three of five solves, best and worst discarded · a PB is a personal best · a DNF (did not finish) is an attempt with no valid result: a popped piece, an unsolved face, an over-limit memorisation · top X% compares against everyone ever ranked in that event, which is fairer than raw rank because event pools differ tenfold.
