Yang Cheng (程阳) has been competing for 5 years. His best event is the Clock: a personal-best single of 4.65, set at Chengdu Spring Open 2025, puts him in the top 3.6% of the 32,048 people who have ever been ranked in the event, and 62nd in China. Until June 2015, no official Clock solve in the world had been that fast. Across 7 competitions since June 2021, he has put 108 official solves on the record across five events. Solve to solve, his 3×3 times vary about 11% around a typical one, an early reading from 5 counted rounds. His Clock best has come down from 13.90 in June 2021 to 4.65, a 67% improvement. Yang has entered seven competitions, more competitions than 88% 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.
