SeHwan Yang (양세환) has been competing for 7 years. His best event is the 3×3: a personal-best single of 8.85, set at Busan Spring 2024, puts him in the top 4.5% of the 284,439 people who have ever been ranked in the event, and 273rd in Republic of Korea. Until May 2008, no official 3×3 solve in the world had been that fast. Across 7 competitions since June 2019, he has put 97 official solves on the record across six events.

SeHwan has entered seven competitions, more competitions than 88% 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.
