Hongbo Zhan (战鸿博)
Pyraminx · top 7.5% of 129,321 all-time · competing since December 2015 · 2015ZHAN97
Hongbo Zhan (战鸿博) has been competing for 11 years. His best event is the Pyraminx: a personal-best single of 3.97, set at Mudanjiang Open 2018, puts him in the top 7.5% of the 129,321 people who have ever been ranked in the event, and 885th in China. Until February 2008, no official Pyraminx solve in the world had been that fast. Across 6 competitions since December 2015, he has put 94 official solves on the record across three events. Solve to solve, his 3×3 times vary about 12% around a typical one, an early reading from 6 counted rounds. That figure sets aside his 4 DNFs. His Pyraminx best has come down from 6.38 in December 2015 to 3.97, a 38% improvement. Hongbo has entered six competitions, more competitions than 86% 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.
