Yen Chu (朱妍) has been competing for 2 years. Her best event is the Pyraminx: a personal-best single of 3.96, set at Legazpi Multi Days 2026, puts her in the top 7.5% of the 130,891 people who have ever been ranked in the event, and 118th in Chinese Taipei. Until February 2008, no official Pyraminx solve in the world had been that fast. Across 10 competitions since September 2024, she has put 177 official solves on the record across eight events. Solve to solve, her 3×3 times vary about 16% around a typical one; 89% of the 36,406 competitors with ten or more counted rounds hold a tighter spread. Her 3×3 best has come down from 15.34 in September 2024 to 10.22, a 33% improvement. Yen 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.
