Jun Hyeok Jang (장준혁) has been competing for 4 years. His best event is the 3×3: a personal-best single of 9.01, set at Suncheon Fall 2023, puts him in the top 4.9% of the 284,439 people who have ever been ranked in the event, and 291st in Republic of Korea. Until May 2008, no official 3×3 solve in the world had been that fast. Across 6 competitions since September 2022, he has put 85 official solves on the record across three events. Solve to solve, his 3×3 times vary about 17% around a typical one, an early reading from 9 counted rounds. His 3×3 best has come down from 12.87 in September 2022 to 9.01, a 30% improvement. Jun has entered six competitions, more competitions than 86% 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.
