Guojie Cao (曹国杰) has been competing for 14 years. His best event is the 2×2: a personal-best single of 2.91, set at Beijing Winter 2019, puts him in the top 13.2% of the 186,767 people who have ever been ranked in the event, and 2,056th in China. Across 15 competitions since November 2012, he has put 257 official solves on the record across six 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.
