Jihoo Yoon (윤지후) has been competing for 4 years. His best event is the 3×3: a personal-best single of 6.33, set at Korean Championship 2024, puts him in the top 0.7% of the 284,439 people who have ever been ranked in the event, and 50th in Republic of Korea. Until May 2011, no official 3×3 solve in the world had been that fast. Across 5 competitions since August 2022, he has put 64 official solves on the record across two 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 8.13 in August 2022 to 6.33, a 22% improvement. Jihoo has entered five competitions, more competitions than 83% 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.
