Yichao Li (李伊超) has been competing for 8 years. His best event is the Pyraminx: a personal-best single of 2.74, set at Michigan 2023, puts him in the top 2.8% of the 129,321 people who have ever been ranked in the event, and 329th in China. Until October 2010, no official Pyraminx solve in the world had been that fast. Across 9 competitions since December 2018, he has put 312 official solves on the record across 13 events.

His 3×3 best has come down from 22.53 in December 2018 to 11.27, a 50% improvement. Yichao has entered nine competitions, more competitions than 91% 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.
