Jiongyang Zheng (郑炯扬) has been competing for 10 years. His best event is the Skewb: a personal-best single of 2.76, set at Chaozhou Open 2017, puts him in the top 3.9% of the 73,281 people who have ever been ranked in the event, and 204th in China. Until February 2014, no official Skewb solve in the world had been that fast. Across 9 competitions since April 2016, he has put 291 official solves on the record across ten events.

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.
