Tsai-Na Kuo (郭采納) has been competing for 8 years. Her best event is the Pyraminx: a personal-best single of 2.35, set at Dream One Cube Open 2019, puts her in the top 1.8% of the 129,321 people who have ever been ranked in the event, and 29th in Chinese Taipei. Until July 2011, no official Pyraminx solve in the world had been that fast. Across 7 competitions since March 2018, she has put 102 official solves on the record across three events. Solve to solve, her 3×3 times vary about 15% around a typical one, an early reading from 9 counted rounds. Her Pyraminx best has come down from 8.41 in June 2018 to 2.35, a 72% improvement. She has entered seven competitions, more competitions than 88% 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.
