Dewei Liu (刘德威)
3×3 · top 0.21% of 288,433 all-time · competing since January 2021 · 2021LIUD01
Dewei Liu (刘德威) has been competing for 6 years. His best event is the 3×3: a personal-best single of 5.39, set at Hangzhou Open 2024, puts him in the top 0.21% of the 288,433 people who have ever been ranked in the event, and 91st in China. Until April 2015, no official 3×3 solve in the world had been that fast. Across 10 competitions since January 2021, he has put 179 official solves on the record across two events. Solve to solve, his 3×3 times vary about 12% around a typical one, steadier than 65% of the 36,406 competitors with ten or more counted rounds. His 3×3 best has come down from 9.18 in January 2021 to 5.39, a 41% improvement. Dewei has entered ten competitions, more competitions than 92% 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.
