Zejin Liu (刘泽锦)
Pyraminx · top 0.19% of 129,321 all-time · competing since April 2021 · 2021LIUZ04
Zejin Liu (刘泽锦) has been competing for 5 years. His best event is the Pyraminx: a personal-best single of 1.26, set at Chengdu Summer 2024, puts him in the top 0.19% of the 129,321 people who have ever been ranked in the event, and 18th in China. Until January 2018, no official Pyraminx solve in the world had been that fast. Across 8 competitions since April 2021, he has put 193 official solves on the record across four events. Solve to solve, his 3×3 times vary about 12% around a typical one, steadier than 77% of the 35,811 competitors with ten or more counted rounds. His Pyraminx best has come down from 2.64 in April 2021 to 1.26, a 52% improvement. Zejin 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.
