SeokHun Choi (최석훈)
3×3 · top 1.6% of 288,433 all-time · competing since October 2023 · 2023CHOI30
SeokHun Choi (최석훈) has been competing for 3 years. His best event is the 3×3: a personal-best single of 7.19, set at We Laugh Pohanghang 2025, puts him in the top 1.6% of the 288,433 people who have ever been ranked in the event, and 100th in Republic of Korea. Until July 2008, no official 3×3 solve in the world had been that fast. Across 9 competitions since October 2023, he has put 251 official solves on the record across nine events. Solve to solve, his 3×3 times vary about 15% around a typical one; 79% of the 36,406 competitors with ten or more counted rounds hold a tighter spread. That figure sets aside his 6 DNFs. His 3×3 best has come down from 13.42 in October 2023 to 7.19, a 46% improvement. SeokHun has entered nine competitions, more competitions than 91% 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.
