Chia-Yen Tu (杜佳姸) has been competing for 3 years. Her best event is the Pyraminx: a personal-best single of 3.24, set at Taiwan Championship 2025, puts her in the top 4.5% of the 129,321 people who have ever been ranked in the event, and 66th in Chinese Taipei. Until February 2008, no official Pyraminx solve in the world had been that fast. Across 10 competitions since June 2023, she has put 248 official solves on the record across five events. Solve to solve, her 3×3 times vary about 17% around a typical one; 97% of the 35,811 competitors with ten or more counted rounds hold a tighter spread. Her 3×3 best has come down from 12.16 in June 2023 to 9.04, a 26% improvement. She 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.
