Guangmei Chen (陈光美)

3×3 · top 0.19% of 284,439 all-time · competing since May 2019 · 2019CHEG04

Guangmei Chen (陈光美) has been competing for 7 years. Her best event is the 3×3: a personal-best single of 5.29, set at Hong Kong Championship 2023, puts her in the top 0.19% of the 284,439 people who have ever been ranked in the event, and 75th in China. Until April 2015, no official 3×3 solve in the world had been that fast. Across 23 competitions since May 2019, she has put 375 official solves on the record across two events. Solve to solve, her 3×3 times vary about 12% around a typical one, steadier than 76% of the 35,811 competitors with ten or more counted rounds. Her 3×3 best has come down from 15.50 in May 2019 to 5.29, a 66% improvement. Guangmei has entered 23 competitions, more competitions than 97% 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.
