Kim Sae Woon (김세운) has been competing for 2 years. His best event is the 3×3: a personal-best single of 8.13, set at Seoul Summer 2026, puts him in the top 3.0% of the 284,439 people who have ever been ranked in the event, and 190th in Republic of Korea. Until July 2008, no official 3×3 solve in the world had been that fast. Across 8 competitions since June 2024, he has put 126 official solves on the record across five events. Solve to solve, his 3×3 times vary about 13% around a typical one; 59% of the 35,811 competitors with ten or more counted rounds hold a tighter spread. His 3×3 best has come down from 11.98 in June 2024 to 8.13, a 32% improvement. Kim 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.
