BuHong Cho (조부홍) has been competing for a year. His best event is the Clock: a personal-best single of 15.91, set at Ansan Favorites 2026, puts him in the top 51.5% of the 32,048 people who have ever been ranked in the event, and 351st in Republic of Korea. Across 7 competitions since January 2025, he has put 68 official solves on the record across eight events. Solve to solve, his 3×3 times vary about 17% around a typical one, an early reading from 6 counted rounds. That figure sets aside his 2 DNFs.

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.
