Sibo Zhou (周嗣博) has been competing for 9 years. His best event is the Skewb: a personal-best single of 3.73, set at China Championship 2018, puts him in the top 9.1% of the 73,281 people who have ever been ranked in the event, and 533rd in China. Until February 2014, no official Skewb solve in the world had been that fast. Across 6 competitions since June 2017, he has put 246 official solves on the record across nine events. Solve to solve, his 3×3 times vary about 11% around a typical one, an early reading from 9 counted rounds. That figure sets aside his 3 DNFs. His 3×3 best has come down from 16.11 in June 2017 to 12.16, a 25% improvement. Sibo has entered six competitions, more competitions than 86% 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.
