3×3 · top 7.1% of 288,433 all-time · competing since February 2024 · 2024JOAL01
Alex Yunhu Jo has been competing for 3 years. His best event is the 3×3: a personal-best single of 9.84, set at Brampton Summer 2026, puts him in the top 7.1% of the 288,433 people who have ever been ranked in the event, and 663rd in Canada. Until October 2007, no official 3×3 solve in the world had been that fast. Across 5 competitions since February 2024, he has put 61 official solves on the record across four events. Solve to solve, his 3×3 times vary about 14% around a typical one; 64% of the 36,406 competitors with ten or more counted rounds hold a tighter spread. His 3×3 best has come down from 13.27 in February 2024 to 9.84, a 26% improvement. Alex has entered five competitions, more competitions than 83% 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.
