Dong-Hyun Kim (김동현)
4×4 · top 8.4% of 83,917 all-time · competing since May 2015 · 2015KIMD02
Dong-Hyun Kim (김동현) has been competing for 11 years. His best event is the 4×4: a personal-best single of 36.71, set at Korean Championship 2018, puts him in the top 8.4% of the 83,917 people who have ever been ranked in the event, and 169th in Republic of Korea. Until October 2009, no official 4×4 solve in the world had been that fast. Across 3 competitions since May 2015, he has put 62 official solves on the record across seven events. Solve to solve, his 3×3 times vary about 14% around a typical one, an early reading from 5 counted rounds. That figure sets aside his 2 DNFs. His 3×3 best has come down from 17.31 in May 2015 to 10.40, a 40% improvement. He has entered three competitions, more competitions than 69% 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.
