Yiheng Chen (陈一衡)

2×2 · top 9.3% of 186,767 all-time · competing since April 2018 · 2018CHEN70

Yiheng Chen (陈一衡) has been competing for 8 years. His best event is the 2×2: a personal-best single of 2.54, set at Chengdu Winter 2019, puts him in the top 9.3% of the 186,767 people who have ever been ranked in the event, and 1,383rd in China. Until February 2008, no official 2×2 solve in the world had been that fast. Across 3 competitions since April 2018, he has put 69 official solves on the record across two events. Solve to solve, his 3×3 times vary about 11% around a typical one, an early reading from 7 counted rounds. His 2×2 best has come down from 4.00 in April 2018 to 2.54, a 36% improvement. Yiheng has entered three competitions, more competitions than 69% 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.
