Kezheng Chen (陈柯铮) has been competing for 10 years. His best event is the 3×3: a personal-best single of 10.35, set at Shijiazhuang Open 2019, puts him in the top 8.5% of the 284,439 people who have ever been ranked in the event, and 3,327th in China. Until May 2007, no official 3×3 solve in the world had been that fast. Across 9 competitions since May 2016, he has put 157 official solves on the record across four events. Solve to solve, his 3×3 times vary about 13% around a typical one; 57% of the 35,811 competitors with ten or more counted rounds hold a tighter spread. His 3×3 best has come down from 16.29 in May 2016 to 10.35, a 36% improvement. Kezheng has entered nine competitions, more competitions than 91% 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.
