Hongbin Xu (许鸿彬)
Clock · top 5.5% of 32,817 all-time · competing since November 2016 · 2016XUHO02
Hongbin Xu (许鸿彬) has been competing for 10 years. His best event is the Clock: a personal-best single of 5.43, set at Rubik's WCA Asian Championship 2024, puts him in the top 5.5% of the 32,817 people who have ever been ranked in the event, and 108th in China. Until December 2011, no official Clock solve in the world had been that fast. Across 7 competitions since November 2016, he has put 48 official solves on the record across two events. Solve to solve, his 3×3 times vary about 19% around a typical one, an early reading from 6 counted rounds. His 3×3 best has come down from 32.86 in November 2016 to 12.77, a 61% improvement. Hongbin has entered seven competitions, more competitions than 88% 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.
