Kai-Yu Hsu (許愷育) has been competing for 11 years. His best event is the 3×3: a personal-best single of 8.63, set at Chiayi Open 2022, puts him in the top 4.0% of the 284,439 people who have ever been ranked in the event, and 231st in Chinese Taipei. Until July 2008, no official 3×3 solve in the world had been that fast. Across 12 competitions since July 2015, he has put 248 official solves on the record across six events. Solve to solve, his 3×3 times vary about 15% around a typical one; 85% of the 35,811 competitors with ten or more counted rounds hold a tighter spread. His 3×3 best has come down from 19.49 in July 2015 to 8.63, a 56% improvement. He has entered twelve competitions, more competitions than 94% 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.
