JiO Han (한지오) has been competing for 3 years. His best event is the 3×3: a personal-best single of 10.32, set at Uhseo Osong 2026, puts him in the top 8.4% of the 284,439 people who have ever been ranked in the event, and 479th in Republic of Korea. Until May 2007, no official 3×3 solve in the world had been that fast. Across 12 competitions since September 2023, he has put 125 official solves on the record across three events. Solve to solve, his 3×3 times vary about 10% around a typical one, steadier than 96% of the 35,811 competitors with ten or more counted rounds. His 3×3 best has come down from 13.70 in October 2023 to 10.32, a 25% improvement. JiO has entered twelve competitions, more competitions than 94% 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.
