Jianhua Yin (尹建桦) has been competing for 11 years. His best event is the 3×3 one-handed: a personal-best single of 13.09, set at Dongguan Summer 2019, puts him in the top 4.6% of the 73,695 people who have ever been ranked in the event, and 402nd in China. Until January 2010, no official 3×3 one-handed solve in the world had been that fast. Across 13 competitions since October 2015, he has put 408 official solves on the record across eight events.

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.
