Chi-Yu Li (李其祐) has been competing for 8 years. His best event is the Square-1: a personal-best single of 8.94, set at Taoyuan Cubing Open 2022, puts him in the top 4.4% of the 25,662 people who have ever been ranked in the event, and 19th in Chinese Taipei. Until October 2010, no official Square-1 solve in the world had been that fast. Across 11 competitions since January 2019, he has put 269 official solves on the record across nine events. Solve to solve, his 3×3 times vary about 14% around a typical one; 67% of the 36,406 competitors with ten or more counted rounds hold a tighter spread. His 3×3 best has come down from 24.92 in January 2019 to 10.35, a 58% improvement. He has entered eleven competitions, more competitions than 93% 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.
