Xuankai Zhang (张轩恺) has been competing for 9 years. His best event is the Pyraminx: a personal-best single of 3.30, set at Ordos Winter 2020, puts him in the top 4.7% of the 129,321 people who have ever been ranked in the event, and 561st in China. Until February 2008, no official Pyraminx solve in the world had been that fast. Across 6 competitions since August 2017, he has put 172 official solves on the record across seven events.

His 3×3 best has come down from 15.65 in August 2017 to 10.03, a 36% improvement. Xuankai 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.
