Zhengzhe Jiang (江政哲)
Pyraminx · top 4.4% of 130,891 all-time · competing since June 2019 · 2019JIAN44
Zhengzhe Jiang (江政哲) has been competing for 7 years. His best event is the Pyraminx: a personal-best single of 3.21, set at Chengdu Summer 2024, puts him in the top 4.4% of the 130,891 people who have ever been ranked in the event, and 542nd in China. Until February 2008, no official Pyraminx solve in the world had been that fast. Across 8 competitions since June 2019, he has put 198 official solves on the record across nine events. Solve to solve, his 3×3 times vary about 11% around a typical one, steadier than 85% of the 36,406 competitors with ten or more counted rounds. That figure sets aside his 3 DNFs. His 3×3 best has come down from 13.62 in June 2019 to 9.21, a 32% improvement. Zhengzhe has entered eight competitions, more competitions than 90% 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.
