YouJoon Hong (홍유준) has been competing for 2 years. His best event is the Clock: a personal-best single of 5.01, set at Korea Open 2025, puts him in the top 4.5% of the 32,048 people who have ever been ranked in the event, and 27th in Republic of Korea. Until April 2015, no official Clock solve in the world had been that fast. Across 3 competitions since September 2024, he has put 62 official solves on the record across five events. Solve to solve, his 3×3 times vary about 8% around a typical one, an early reading from 5 counted rounds. His 3×3 best has come down from 13.61 in September 2024 to 10.04, a 26% improvement. YouJoon has entered three competitions, more competitions than 69% 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.
