Xinwei Zhou (周欣伟) has been competing for 10 years. His best event is the Pyraminx: a personal-best single of 2.10, set at Nanjing Spring 2017, puts him in the top 1.3% of the 129,321 people who have ever been ranked in the event, and 141st in China. Until July 2011, no official Pyraminx solve in the world had been that fast. Across 32 competitions since April 2016, he has put 1,207 official solves on the record across eleven events.

His 3×3 best has come down from 14.98 in April 2016 to 8.16, a 46% improvement. Xinwei has entered 32 competitions, more competitions than 98% 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.
