Dong Xu (徐栋)
Pyraminx · top 9.8% of 130,891 all-time · competing since November 2016 · 2016XUDO01
Dong Xu (徐栋) has been competing for 10 years. His best event is the Pyraminx: a personal-best single of 4.41, set at Wuhan Open 2016, puts him in the top 9.8% of the 130,891 people who have ever been ranked in the event, and 1,172nd in China. Until September 2006, no official Pyraminx solve in the world had been that fast. Across 9 competitions since November 2016, he has put 94 official solves on the record across four events. Solve to solve, his 3×3 times vary about 17% around a typical one, an early reading from 9 counted rounds. That figure sets aside his 4 DNFs. His 3×3 best has come down from 25.63 in November 2016 to 18.35, a 28% improvement. Dong has entered nine competitions, more competitions than 91% 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.
