Seongung Yu (유성웅)
3×3 · top 8.9% of 288,433 all-time · competing since November 2024 · 2024YUSE03
Seongung Yu (유성웅) has been competing for a year. His best event is the 3×3: a personal-best single of 10.47, set at Daejeon Spring 2025, puts him in the top 8.9% of the 288,433 people who have ever been ranked in the event, and 514th in Republic of Korea. Until February 2007, no official 3×3 solve in the world had been that fast. Across 5 competitions since November 2024, he has put 52 official solves on the record across two events. Solve to solve, his 3×3 times vary about 16% around a typical one, an early reading from 8 counted rounds. That figure sets aside his 3 DNFs. His 3×3 best has come down from 13.50 in November 2024 to 10.47, a 22% improvement. Seongung has entered five competitions, more competitions than 83% 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.
