Pyraminx · top 10.0% of 129,321 all-time · competing since March 2017 · 2017ZHAN19

Lu Zhang (张陆) has been competing for 10 years. His best event is the Pyraminx: a personal-best single of 4.45, set at Nanjing Spring 2018, puts him in the top 10.0% of the 129,321 people who have ever been ranked in the event, and 1,179th in China. Until September 2006, no official Pyraminx solve in the world had been that fast. Across 23 competitions since March 2017, he has put 514 official solves on the record across nine events. Solve to solve, his 3×3 times vary about 10% around a typical one, steadier than 94% of the 35,811 competitors with ten or more counted rounds. His 3×3 best has come down from 15.10 in March 2017 to 11.80, a 22% improvement. Lu has entered 23 competitions, more competitions than 97% 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.
