Bojun Zhang (张博俊)
Skewb · top 7.5% of 73,281 all-time · competing since December 2014 · 2014ZHAN62
Bojun Zhang (张博俊) has been competing for 12 years. His best event is the Skewb: a personal-best single of 3.46, set at Shenyang Spring 2017, puts him in the top 7.5% of the 73,281 people who have ever been ranked in the event, and 425th in China. Until February 2014, no official Skewb solve in the world had been that fast. Across 13 competitions since December 2014, he has put 357 official solves on the record across twelve events. Solve to solve, his 3×3 times vary about 13% around a typical one, steadier than 60% of the 35,811 competitors with ten or more counted rounds. That figure sets aside his 7 DNFs. His 3×3 best has come down from 32.83 in December 2014 to 12.21, a 63% improvement. Bojun has entered 13 competitions, more competitions than 94% 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.
