Jaeryung Lim (임재령) has been competing for 3 years. His best event is the 3×3: a personal-best single of 7.57, set at Ansan Summer 2024, puts him in the top 2.1% of the 284,439 people who have ever been ranked in the event, and 123rd in Republic of Korea. Until July 2008, no official 3×3 solve in the world had been that fast. Across 10 competitions since March 2023, he has put 156 official solves on the record across eight events. Solve to solve, his 3×3 times vary about 14% around a typical one; 75% of the 35,811 competitors with ten or more counted rounds hold a tighter spread. His 3×3 best has come down from 10.55 in December 2023 to 7.57, a 28% improvement. Jaeryung has entered ten competitions, more competitions than 92% of everyone who has ever competed.

The story so far

Competitions

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.
