De-Yuan Meng (孟德元) has been competing for 3 years. His best event is the 3×3: a personal-best single of 7.52, set at Rubik's WCA World Championship 2025, puts him in the top 2.0% of the 284,439 people who have ever been ranked in the event, and 116th in Chinese Taipei. Until July 2008, no official 3×3 solve in the world had been that fast. Across 16 competitions since December 2023, he has put 351 official solves on the record across six events.

His 3×3 best has come down from 14.15 in December 2023 to 7.52, a 47% improvement. He has entered 16 competitions, more competitions than 96% 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.
