Shouheng Yin (尹守恒) has been competing for 7 years. His best event is the Skewb: a personal-best single of 4.81, set at Hangzhou Open 2024, puts him in the top 16.7% of the 73,281 people who have ever been ranked in the event, and 1,032nd in China. Across 7 competitions since November 2019, he has put 111 official solves on the record across nine events. Solve to solve, his 3×3 times vary about 9% around a typical one, an early reading from 6 counted rounds. That figure sets aside his 4 DNFs.

The story so far

Competitions

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.
