3×3 · top 21.1% of 284,439 all-time · competing since June 2018 · 2018XIEC01
Chengming Xie (谢丞铭) has been competing for 8 years. His best event is the 3×3: a personal-best single of 14.03, set at Beijing Winter 2025, puts him in the top 21.1% of the 284,439 people who have ever been ranked in the event, and 8,135th in China. Across 12 competitions since June 2018, he has put 125 official solves on the record across three events. Solve to solve, his 3×3 times vary about 12% around a typical one, steadier than 65% of the 35,811 competitors with ten or more counted rounds. That figure sets aside his 3 DNFs. His 3×3 best has come down from 1:07.64 in June 2018 to 14.03, a 79% improvement. Chengming has entered twelve 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.
