Seo Yeung Jin (서영진) has been competing for 4 years. His best event is the 3×3: a personal-best single of 8.63, set at Anyang Haseyo 2025, puts him in the top 4.0% of the 288,433 people who have ever been ranked in the event, and 244th in Republic of Korea. Until July 2008, no official 3×3 solve in the world had been that fast. Across 2 competitions since May 2023, he has put 19 official solves on the record across two events. His 3×3 best has come down from 19.46 in May 2023 to 8.63, a 56% improvement. Seo has entered two 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.
