Ethan Yu has been competing for a year. His best event is the 3×3: a personal-best single of 10.33, set at Davis Big Summer 2026, puts him in the top 8.4% of the 284,439 people who have ever been ranked in the event, and 482nd in Republic of Korea. Until May 2007, no official 3×3 solve in the world had been that fast. Across 12 competitions since November 2024, he has put 222 official solves on the record across six events. Solve to solve, his 3×3 times vary about 10% around a typical one, steadier than 95% of the 35,811 competitors with ten or more counted rounds. His 3×3 best has come down from 23.95 in November 2024 to 10.33, a 57% improvement. Ethan has entered twelve competitions, more competitions than 94% 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.
