Chenchang Yang (杨宸畅) has been competing for 9 years. His best event is the Skewb: a personal-best single of 1.82, set at Xuzhou Open 2018, puts him in the top 0.96% of the 73,281 people who have ever been ranked in the event, and 41st in China. Until December 2014, no official Skewb solve in the world had been that fast. Across 13 competitions since April 2017, he has put 238 official solves on the record across ten events.

His 3×3 best has come down from 14.41 in April 2017 to 9.42, a 35% improvement. Chenchang has entered 13 competitions, more competitions than 94% 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.
