Xuanyu Cai (蔡暄予)
3×3 · top 7.5% of 284,439 all-time · competing since March 2023 · 2023CAIX01
Xuanyu Cai (蔡暄予) has been competing for 4 years. His best event is the 3×3: a personal-best single of 10.02, set at Nanchang Summer 2026, puts him in the top 7.5% of the 284,439 people who have ever been ranked in the event, and 2,930th in China. Until May 2007, no official 3×3 solve in the world had been that fast. Across 10 competitions since March 2023, he has put 165 official solves on the record across four events. Solve to solve, his 3×3 times vary about 11% around a typical one, steadier than 85% of the 35,811 competitors with ten or more counted rounds. His 3×3 best has come down from 14.18 in March 2023 to 10.02, a 29% improvement. Xuanyu 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.
