Hao Zheng (郑昊) has been competing for 10 years. His best event is the Pyraminx: a personal-best single of 4.07, set at Xiamen Open 2017, puts him in the top 8.0% of the 129,321 people who have ever been ranked in the event, and 953rd in China. Until February 2008, no official Pyraminx solve in the world had been that fast. Across 3 competitions since December 2016, he has put 84 official solves on the record across three events. Solve to solve, his 3×3 times vary about 9% around a typical one, an early reading from 5 counted rounds. His 2×2 best has come down from 5.55 in December 2016 to 3.81, a 31% improvement. Hao has entered three competitions, more competitions than 69% 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.
