Byeong-Wook Jeong has been competing for 10 years. His best event is the 3×3: a personal-best single of 8.71, set at Osan Summer 2025, puts him in the top 4.2% of the 284,439 people who have ever been ranked in the event, and 250th in Republic of Korea. Until July 2008, no official 3×3 solve in the world had been that fast. Across 7 competitions since May 2016, he has put 95 official solves on the record across six events. Solve to solve, his 3×3 times vary about 14% around a typical one; 74% of the 35,811 competitors with ten or more counted rounds hold a tighter spread. His 3×3 best has come down from 17.89 in May 2016 to 8.71, a 51% improvement. He 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.
