3×3 · top 4.7% of 288,433 all-time · competing since August 2025 · 2025CHEC04
Chia Cheng-You (謝承佑) has been competing for a year. His best event is the 3×3: a personal-best single of 8.92, set at Shin Kong Cube Open - Kaohsiung 2026, puts him in the top 4.7% of the 288,433 people who have ever been ranked in the event, and 281st in Chinese Taipei. Until May 2008, no official 3×3 solve in the world had been that fast. Across 8 competitions since August 2025, he has put 64 official solves on the record across three events. Solve to solve, his 3×3 times vary about 12% around a typical one, steadier than 72% of the 36,406 competitors with ten or more counted rounds. His 3×3 best has come down from 11.15 in August 2025 to 8.92, a 20% improvement. Chia has entered eight competitions, more competitions than 90% 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.
