Zejia Ren (任泽佳)
3×3 · top 8.8% of 288,433 all-time · competing since July 2017 · 2017RENZ01
Zejia Ren (任泽佳) has been competing for 9 years. His best event is the 3×3: a personal-best single of 10.42, set at Fuzhou Spring 2019, puts him in the top 8.8% of the 288,433 people who have ever been ranked in the event, and 3,476th in China. Until February 2007, no official 3×3 solve in the world had been that fast. Across 6 competitions since July 2017, he has put 248 official solves on the record across eleven events. Solve to solve, his 3×3 times vary about 12% around a typical one, steadier than 65% of the 36,406 competitors with ten or more counted rounds. That figure sets aside his 3 DNFs. His 3×3 best has come down from 14.29 in July 2017 to 10.42, a 27% improvement. Zejia 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.
