Yimeng Xu (徐已檬)

3×3 · top 1.9% of 284,439 all-time · competing since July 2019 · 2019XUYI04

Yimeng Xu (徐已檬) has been competing for 7 years. Her best event is the 3×3: a personal-best single of 7.47, set at Rubik's WCA World Championship 2023, puts her in the top 1.9% of the 284,439 people who have ever been ranked in the event, and 685th in China. Until July 2008, no official 3×3 solve in the world had been that fast. Across 8 competitions since July 2019, she has put 129 official solves on the record across four events. Solve to solve, her 3×3 times vary about 11% around a typical one, steadier than 87% of the 35,811 competitors with ten or more counted rounds. Her 3×3 best has come down from 15.96 in July 2019 to 7.47, a 53% improvement. Yimeng has entered eight competitions, more competitions than 90% of everyone who has ever competed.

Best single per competition, 3×3. Faster is higher — the axis is the right way up.

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.
