Juncheng Zhang (章骏成) has been competing for 2 years. His best event is the Pyraminx: a personal-best single of 2.06, set at Deqing Small & Special 2026, puts him in the top 1.3% of the 129,321 people who have ever been ranked in the event, and 134th in China. Until July 2011, no official Pyraminx solve in the world had been that fast. Across 5 competitions since March 2024, he has put 98 official solves on the record across four events. Solve to solve, his 3×3 times vary about 16% around a typical one, an early reading from 8 counted rounds. Juncheng has entered five competitions, more competitions than 83% 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.
