Chen Cheng (程晨) has been competing for 8 years. His best event is the 2×2: a personal-best single of 1.86, set at Shenzhen Cubing 10th Anniversary 2019, puts him in the top 3.9% of the 186,767 people who have ever been ranked in the event, and 522nd in China. Until February 2008, no official 2×2 solve in the world had been that fast. Across 6 competitions since May 2018, he has put 180 official solves on the record across five events. Solve to solve, his 3×3 times vary about 12% around a typical one, steadier than 70% of the 35,811 competitors with ten or more counted rounds. His 2×2 best has come down from 3.99 in May 2018 to 1.86, a 53% improvement. Chen 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.
