Chenggang Yao (姚成刚)

3×3 · top 7.9% of 284,439 all-time · competing since March 2019 · 2019YAOC01

Chenggang Yao (姚成刚) has been competing for 7 years. His best event is the 3×3: a personal-best single of 10.15, set at Hangzhou Open 2024, puts him in the top 7.9% of the 284,439 people who have ever been ranked in the event, and 3,085th in China. Until May 2007, no official 3×3 solve in the world had been that fast. Across 4 competitions since March 2019, he has put 40 official solves on the record across two events. Solve to solve, his 3×3 times vary about 14% around a typical one, an early reading from 5 counted rounds. That figure sets aside his 2 DNFs. Chenggang has entered four competitions, more competitions than 78% 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.
