Xukai Mei (梅栩恺) has been competing for 7 years. His best event is the Pyraminx: a personal-best single of 1.91, set at Kunshan Open 2024, puts him in the top 0.99% of the 129,321 people who have ever been ranked in the event, and 111th in China. Until April 2012, no official Pyraminx solve in the world had been that fast. Across 11 competitions since October 2019, he has put 302 official solves on the record across five events.

His 3×3 best has come down from 35.12 in October 2019 to 7.77, a 78% improvement. Xukai has entered eleven competitions, more competitions than 93% 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.
