Guobin Zhang (张国斌) has been competing for 12 years. His best event is the Pyraminx: a personal-best single of 4.15, set at Nanjing Spring 2017, puts him in the top 8.4% of the 129,321 people who have ever been ranked in the event, and 1,010th in China. Until February 2008, no official Pyraminx solve in the world had been that fast. Across 6 competitions since July 2014, he has put 149 official solves on the record across five events. Solve to solve, his 3×3 times vary about 11% around a typical one, steadier than 89% of the 35,811 competitors with ten or more counted rounds. Guobin 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.
