Yu Zhou (周煜) has been competing for 9 years. His best event is the Pyraminx: a personal-best single of 3.82, set at Lishui University Open 2018, puts him in the top 6.8% of the 129,321 people who have ever been ranked in the event, and 812th in China. Until February 2008, no official Pyraminx solve in the world had been that fast. Across 15 competitions since July 2017, he has put 400 official solves on the record across 17 events. Solve to solve, his 3×3 times vary about 10% around a typical one, steadier than 97% of the 35,811 competitors with ten or more counted rounds. His 2×2 best has come down from 4.49 in July 2017 to 2.76, a 39% improvement. Yu has entered 15 competitions, more competitions than 95% 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.
