Seungheon Lee has been competing for 3 years. His best event is the 2×2: a personal-best single of 1.32, set at Korean Championship 2025, puts him in the top 1.4% of the 186,767 people who have ever been ranked in the event, and 34th in Republic of Korea. Until November 2008, no official 2×2 solve in the world had been that fast. Across 12 competitions since June 2023, he has put 194 official solves on the record across five events. Solve to solve, his 3×3 times vary about 11% around a typical one, steadier than 85% of the 35,811 competitors with ten or more counted rounds. His 3×3 best has come down from 18.95 in June 2023 to 8.79, a 54% improvement. Seungheon has entered twelve competitions, more competitions than 94% 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.
