Runwei Xu (许润玮)

3×3 · top 9.2% of 284,439 all-time · competing since April 2018 · 2018XURU01

Runwei Xu (许润玮) has been competing for 8 years. His best event is the 3×3: a personal-best single of 10.58, set at Chengdu New Year Afternoon 2021, puts him in the top 9.2% of the 284,439 people who have ever been ranked in the event, and 3,606th in China. Until August 2006, no official 3×3 solve in the world had been that fast. Across 6 competitions since April 2018, he has put 116 official solves on the record across five events. Solve to solve, his 3×3 times vary about 15% around a typical one, an early reading from 7 counted rounds. That figure sets aside his 2 DNFs. His 3×3 best has come down from 27.36 in April 2018 to 10.58, a 61% improvement. Runwei has entered six competitions, more competitions than 86% of everyone who has ever competed.

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.
