Jo Han-Hyuk (조한혁) has been competing for 18 years. His best event is the 2×2: a personal-best single of 2.33, set at Korea Cube Championship 2010, puts him in the top 7.4% of the 189,179 people who have ever been ranked in the event, and 212th in Republic of Korea. Until February 2008, no official 2×2 solve in the world had been that fast. Across 7 competitions since July 2008, he has put 228 official solves on the record across seven events.

His 3×3 best has come down from 13.58 in July 2008 to 10.75, a 21% improvement. Jo 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.
