Zekang Xia (夏泽康) has been competing for 10 years. His best event is the Skewb: a personal-best single of 1.88, set at WCA World Championship 2019, puts him in the top 1.1% of the 73,281 people who have ever been ranked in the event, and 45th in China. Until December 2014, no official Skewb solve in the world had been that fast. Across 19 competitions since October 2016, he has put 461 official solves on the record across eight events.

His 3×3 best has come down from 28.84 in October 2016 to 7.69, a 73% improvement. Zekang has entered 19 competitions, more competitions than 97% 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.
