Chunyu Zhang (张春雨) has been competing for 15 years. His best event is the Pyraminx: a personal-best single of 2.88, set at Nanjing Spring 2015, puts him in the top 3.2% of the 129,321 people who have ever been ranked in the event, and 379th in China.

Best single per competition, 3×3. Faster is higher — the axis is the right way up.

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.
