Sophie Chan

2×2 · top 0.64% of 186,767 all-time · competing since November 2014 · 2014CHAN23

Sophie Chan has been competing for 12 years. Her best event is the 2×2: a personal-best single of 1.04, set at Berkeley Winter 2018, puts her in the top 0.64% of the 186,767 people who have ever been ranked in the event, and 266th in the United States. Until November 2008, no official 2×2 solve in the world had been that fast. Across 27 competitions since November 2014, she has put 1,065 official solves on the record across 14 events. Solve to solve, her 3×3 times vary about 12% around a typical one, steadier than 74% of the 35,811 competitors with ten or more counted rounds. Her 3×3 best has come down from 14.01 in November 2014 to 7.14, a 49% improvement. Sophie has entered 27 competitions, more competitions than 98% 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.
