Jungwon Cho (조정원) has been competing for a year. His best event is the 2×2: a personal-best single of 2.48, set at Korea Open 2026, puts him in the top 8.8% of the 189,179 people who have ever been ranked in the event, and 258th in Republic of Korea. Until February 2008, no official 2×2 solve in the world had been that fast. Across 6 competitions since May 2025, he has put 120 official solves on the record across five events. Solve to solve, his 3×3 times vary about 14% around a typical one, an early reading from 7 counted rounds. His 2×2 best has come down from 3.89 in May 2025 to 2.48, a 36% improvement. Jungwon has entered six competitions, more competitions than 86% 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.
