Clock · top 7.6% of 32,048 all-time · competing since April 2024 · 2024HYUN04
Dayu Hyun (현다유) has been competing for 2 years. His best event is the Clock: a personal-best single of 6.12, set at Osan Summer 2025, puts him in the top 7.6% of the 32,048 people who have ever been ranked in the event, and 50th in Republic of Korea. Until July 2011, no official Clock solve in the world had been that fast. Across 8 competitions since April 2024, he has put 92 official solves on the record across five events. Solve to solve, his 3×3 times vary about 14% around a typical one; 78% of the 35,811 competitors with ten or more counted rounds hold a tighter spread. Dayu has entered eight competitions, more competitions than 90% 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.
