Pyraminx · top 6.3% of 129,321 all-time · competing since January 2017 · 2017GUOZ01

Ziming Guo (郭子鸣) has been competing for 10 years. His best event is the Pyraminx: a personal-best single of 3.72, set at Xi'an New Year 2020, puts him in the top 6.3% of the 129,321 people who have ever been ranked in the event, and 750th in China. Until February 2008, no official Pyraminx solve in the world had been that fast. Across 9 competitions since January 2017, he has put 248 official solves on the record across eight events. Solve to solve, his 3×3 times vary about 14% around a typical one; 75% of the 35,811 competitors with ten or more counted rounds hold a tighter spread. His 3×3 best has come down from 19.08 in January 2017 to 10.60, a 44% improvement. Ziming has entered nine competitions, more competitions than 91% 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.
