3×3 · top 8.0% of 284,439 all-time · competing since May 2022 · 2022JAYJ01
Jung Jay (정재이) has been competing for 4 years. His best event is the 3×3: a personal-best single of 10.18, set at Anyang Haseyo 2025, puts him in the top 8.0% of the 284,439 people who have ever been ranked in the event, and 457th in Republic of Korea. Until May 2007, no official 3×3 solve in the world had been that fast. Across 12 competitions since May 2022, he has put 139 official solves on the record across three events. Solve to solve, his 3×3 times vary about 11% around a typical one, steadier than 90% of the 35,811 competitors with ten or more counted rounds. His 3×3 best has come down from 22.85 in May 2022 to 10.18, a 55% improvement. Jung 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.
