Yiyu Cao (曹轶予) has been competing for 8 years. His best event is the 3×3: a personal-best single of 15.96, set at Shanghai Open 2019, puts him in the top 27.7% of the 284,439 people who have ever been ranked in the event, and 10,274th in China. Across 5 competitions since December 2018, he has put 60 official solves on the record across six events. Solve to solve, his 3×3 times vary about 7% around a typical one, an early reading from 5 counted rounds. That figure sets aside his 2 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.
