Zhaolun Duan (段兆伦)
Skewb · top 5.7% of 73,281 all-time · competing since April 2015 · 2015DUAN01
Zhaolun Duan (段兆伦) has been competing for 11 years. His best event is the Skewb: a personal-best single of 3.15, set at Chengdu Winter 2019, puts him in the top 5.7% of the 73,281 people who have ever been ranked in the event, and 323rd in China. Until February 2014, no official Skewb solve in the world had been that fast. Across 5 competitions since April 2015, he has put 75 official solves on the record across six events. Solve to solve, his 3×3 times vary about 13% around a typical one, an early reading from 7 counted rounds. That figure sets aside his 2 DNFs. His 3×3 best has come down from 22.21 in April 2015 to 12.14, a 45% improvement. Zhaolun has entered five competitions, more competitions than 83% 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.
