Xiaoran Zheng (郑晓然) has been competing for 14 years. His best event is the Pyraminx: a personal-best single of 3.40, set at Guiyang Open 2024, puts him in the top 5.1% of the 129,321 people who have ever been ranked in the event, and 608th in China. Until February 2008, no official Pyraminx solve in the world had been that fast. Across 18 competitions since August 2012, he has put 445 official solves on the record across eight events.

His 3×3 best has come down from 15.55 in August 2012 to 11.09, a 29% improvement. Xiaoran has entered 18 competitions, more competitions than 96% 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.
