SunEum Yum (염선음) has been competing for 3 years. His best event is the 2×2: a personal-best single of 2.43, set at Brown Fall Seongnam 2024, puts him in the top 8.2% of the 186,767 people who have ever been ranked in the event, and 236th in Republic of Korea. Until February 2008, no official 2×2 solve in the world had been that fast. Across 8 competitions since January 2024, he has put 120 official solves on the record across six events. Solve to solve, his 3×3 times vary about 11% around a typical one, steadier than 84% of the 35,811 competitors with ten or more counted rounds. His 3×3 best has come down from 19.76 in January 2024 to 11.33, a 43% improvement. SunEum 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.
