JiHun Yim (임지훈) has been competing for 3 years. His best event is the 3×3 blindfolded: a personal-best single of 20.14, set at Cube Camp in Jeju 2026, puts him in the top 1.4% of the 12,178 people who have ever been ranked in the event, and 5th in Republic of Korea. Until November 2016, no official 3×3 blindfolded solve in the world had been that fast. Across 20 competitions since May 2023, he has put 265 official solves on the record across eleven 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 11.11 in May 2023 to 7.99, a 28% improvement. JiHun has entered 20 competitions, more competitions than 97% 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.
