Haoxi Zheng (郑浩禧)

Pyraminx · top 4.1% of 129,321 all-time · competing since March 2017 · 2017ZHEN09

Haoxi Zheng (郑浩禧) has been competing for 10 years. His best event is the Pyraminx: a personal-best single of 3.13, set at Maoming Open 2019, puts him in the top 4.1% of the 129,321 people who have ever been ranked in the event, and 496th in China. Until February 2008, no official Pyraminx solve in the world had been that fast. Across 6 competitions since March 2017, he has put 176 official solves on the record across seven events. Solve to solve, his 3×3 times vary about 11% around a typical one, steadier than 87% of the 35,811 competitors with ten or more counted rounds. His 3×3 best has come down from 13.57 in March 2017 to 8.69, a 36% improvement. Haoxi has entered six competitions, more competitions than 86% of everyone who has ever competed.

The story so far

Competitions

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.
