Kai-Yu Tsai

Pyraminx · top 23.4% of 129,321 all-time · competing since February 2023 · 2023TSAI01

Kai-Yu Tsai has been competing for 4 years. His best event is the Pyraminx: a personal-best single of 6.45, set at Ontario Championship 2024, puts him in the top 23.4% of the 129,321 people who have ever been ranked in the event, and 342nd in Chinese Taipei. Across 9 competitions since February 2023, he has put 109 official solves on the record across eight events. Solve to solve, his 3×3 times vary about 21% around a typical one; 99% of the 35,811 competitors with ten or more counted rounds hold a tighter spread. That figure sets aside his 5 DNFs. His 3×3 best has come down from 47.47 in February 2023 to 16.18, a 66% improvement. He has entered nine competitions, more competitions than 91% of everyone who has ever competed.

The story so far

Competitions

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.
