Zhengyi Zhang (张政一) has been competing for 8 years. His best event is the Skewb: a personal-best single of 3.16, set at Shenyang New Year 2019, puts him in the top 5.8% of the 74,164 people who have ever been ranked in the event, and 330th in China. Until February 2014, no official Skewb solve in the world had been that fast. Across 6 competitions since April 2018, he has put 164 official solves on the record across six events. Solve to solve, his 3×3 times vary about 13% around a typical one, steadier than 58% of the 36,406 competitors with ten or more counted rounds. His 3×3 best has come down from 22.08 in April 2018 to 11.56, a 48% improvement. Zhengyi 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.
