Dayoung Yoon (윤다영) has been competing for 3 years. Her best event is the 2×2: a personal-best single of 2.37, set at Korea Open 2025, puts her in the top 7.7% of the 186,767 people who have ever been ranked in the event, and 216th in Republic of Korea. Until February 2008, no official 2×2 solve in the world had been that fast. Across 3 competitions since May 2023, she has put 40 official solves on the record across two events. Solve to solve, her 3×3 times vary about 10% around a typical one, an early reading from 5 counted rounds. Her 3×3 best has come down from 16.01 in May 2023 to 11.30, a 29% improvement. Dayoung has entered three competitions, more competitions than 69% 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.
