3×3 · top 6.8% of 284,439 all-time · competing since August 2019 · 2019MINJ02
Ko Minjun (고민준) has been competing for 7 years. His best event is the 3×3: a personal-best single of 9.75, set at Rubik's WCA World Championship 2023, puts him in the top 6.8% of the 284,439 people who have ever been ranked in the event, and 397th in Republic of Korea. Until November 2007, no official 3×3 solve in the world had been that fast. Across 3 competitions since August 2019, he has put 40 official solves on the record across two events. Solve to solve, his 3×3 times vary about 15% around a typical one, an early reading from 5 counted rounds. His 3×3 best has come down from 12.60 in August 2019 to 9.75, a 23% improvement. Ko 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.
