3×3 · top 2.2% of 284,439 all-time · competing since June 2017 · 2017HUAN46

Chengdong Huang (黄呈栋) has been competing for 9 years. His best event is the 3×3: a personal-best single of 7.63, set at Quanzhou Open 2018, puts him in the top 2.2% of the 284,439 people who have ever been ranked in the event, and 790th in China. Until July 2008, no official 3×3 solve in the world had been that fast. Across 2 competitions since June 2017, he has put 41 official solves on the record across four events. Solve to solve, his 3×3 times vary about 17% around a typical one, an early reading from 5 counted rounds. His 3×3 best has come down from 10.34 in June 2017 to 7.63, a 26% improvement. Chengdong has entered two competitions.

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.
