Choi Sung-Hyun (최성현)
3×3 · top 9.4% of 284,439 all-time · competing since October 2015 · 2015SUNG02
Choi Sung-Hyun (최성현) has been competing for 11 years. His best event is the 3×3: a personal-best single of 10.64, set at Seoul Winter 2019, puts him in the top 9.4% of the 284,439 people who have ever been ranked in the event, and 534th in Republic of Korea. Until August 2006, no official 3×3 solve in the world had been that fast. Across 9 competitions since October 2015, he has put 145 official solves on the record across four events. Solve to solve, his 3×3 times vary about 11% around a typical one, steadier than 92% of the 35,811 competitors with ten or more counted rounds. His 3×3 best has come down from 14.91 in October 2015 to 10.64, a 29% improvement. Choi 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.
