Sizhe Ren (任思哲) has been competing for 12 years. His best event is the Skewb: a personal-best single of 2.36, set at Shanghai Winter 2018, puts him in the top 2.4% of the 73,281 people who have ever been ranked in the event, and 125th in China. Until February 2014, no official Skewb solve in the world had been that fast. Across 15 competitions since December 2014, he has put 499 official solves on the record across eleven events. Solve to solve, his 3×3 times vary about 13% around a typical one, steadier than 60% of the 35,811 competitors with ten or more counted rounds. His 3×3 best has come down from 16.25 in December 2014 to 9.70, a 40% improvement. Sizhe has entered 15 competitions, more competitions than 95% 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.
