Chunjie Shan (单淳劼) has been competing for 13 years. His best event is the 3×3 blindfolded: a personal-best single of 24.81, set at China Championship 2018, puts him in the top 2.9% of the 12,178 people who have ever been ranked in the event, and 44th in China. Until June 2013, no official 3×3 blindfolded solve in the world had been that fast. Across 10 competitions since July 2013, he has put 57 official solves on the record across six events. His 3×3 blindfolded best has come down from 1:22.19 in May 2014 to 24.81, a 70% improvement. Chunjie has entered ten competitions, more competitions than 92% of everyone who has ever competed.

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.
