Yau Chou
2×2 · top 3.8% of 186,767 all-time · competing since June 2022 · 2022CHOU04
Yau Chou has been competing for 4 years. Her best event is the 2×2: a personal-best single of 1.84, set at Bristol June 2025, puts her in the top 3.8% of the 186,767 people who have ever been ranked in the event, and 48th in Hong Kong, China. Until February 2008, no official 2×2 solve in the world had been that fast. Across 7 competitions since June 2022, she has put 175 official solves on the record across four events. Solve to solve, her 3×3 times vary about 12% around a typical one, steadier than 79% of the 35,811 competitors with ten or more counted rounds. Her 3×3 best has come down from 10.28 in June 2022 to 8.77, a 15% improvement. Yau has entered seven competitions, more competitions than 88% of everyone who has ever competed.

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.
