Zhenghan Jiao (焦峥涵)
Skewb · top 3.2% of 73,281 all-time · competing since December 2018 · 2018JIAO03
Zhenghan Jiao (焦峥涵) has been competing for 8 years. His best event is the Skewb: a personal-best single of 2.58, set at Chengdu Summer 2024, puts him in the top 3.2% of the 73,281 people who have ever been ranked in the event, and 170th in China. Until February 2014, no official Skewb solve in the world had been that fast. Across 5 competitions since December 2018, he has put 155 official solves on the record across seven events. Solve to solve, his 3×3 times vary about 10% around a typical one, an early reading from 7 counted rounds. That figure sets aside his 2 DNFs. His Skewb best has come down from 3.56 in March 2019 to 2.58, a 28% improvement. Zhenghan has entered five competitions, more competitions than 83% 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.
