JeongWon Jung (정정원)

2×2 · top 4.3% of 189,179 all-time · competing since February 2024 · 2024JUNG04

JeongWon Jung (정정원) has been competing for 3 years. His best event is the 2×2: a personal-best single of 1.92, set at Uhseo Osong 2026, puts him in the top 4.3% of the 189,179 people who have ever been ranked in the event, and 117th in Republic of Korea. Until February 2008, no official 2×2 solve in the world had been that fast. Across 15 competitions since February 2024, he has put 409 official solves on the record across 13 events. Solve to solve, his 3×3 times vary about 12% around a typical one, steadier than 62% of the 36,406 competitors with ten or more counted rounds. That figure sets aside his 4 DNFs. His 3×3 best has come down from 37.89 in February 2024 to 9.27, a 76% improvement. JeongWon has entered 15 competitions, more competitions than 95% 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.
