Chunshuai Hu (胡春帅) has been competing for a year. His best event is the Pyraminx: a personal-best single of 2.37, set at Zhengzhou Zest 2025, puts him in the top 1.9% of the 129,321 people who have ever been ranked in the event, and 219th in China. Until April 2011, no official Pyraminx solve in the world had been that fast. Across 3 competitions since January 2025, he has put 81 official solves on the record across five events. Solve to solve, his 3×3 times vary about 20% around a typical one, an early reading from 6 counted rounds. His 3×3 best has come down from 10.44 in January 2025 to 8.73, a 16% improvement. Chunshuai has entered three competitions, more competitions than 69% 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.
