3×3 · top 7.1% of 284,439 all-time · competing since October 2018 · 2018KOYU01

Yu-Wei Ko (柯昱瑋) has been competing for 8 years. His best event is the 3×3: a personal-best single of 9.89, set at Zhuyuangang Open 2020, puts him in the top 7.1% of the 284,439 people who have ever been ranked in the event, and 426th in Chinese Taipei. Until May 2007, no official 3×3 solve in the world had been that fast. Across 6 competitions since October 2018, he has put 115 official solves on the record across five events. Solve to solve, his 3×3 times vary about 12% around a typical one, steadier than 62% of the 35,811 competitors with ten or more counted rounds. His 3×3 best has come down from 14.14 in October 2018 to 9.89, a 30% improvement. He has entered six competitions, more competitions than 86% 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.
