Sumin Chae (채수민) has been competing for 10 years. His best event is the 3×3: a personal-best single of 7.59, set at Korean Championship 2018, puts him in the top 2.1% of the 284,439 people who have ever been ranked in the event, and 127th in Republic of Korea. Until July 2008, no official 3×3 solve in the world had been that fast. Across 11 competitions since May 2016, he has put 190 official solves on the record across seven events.

His 3×3 best has come down from 16.73 in May 2016 to 7.59, a 55% improvement. Sumin has entered eleven competitions, more competitions than 93% 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.
