Leon Cai

2×2 · top 9.3% of 186,767 all-time · competing since April 2023 · 2023CAIL01

Leon Cai has been competing for 3 years. His best event is the 2×2: a personal-best single of 2.54, set at Battle of Waterloo 2024, puts him in the top 9.3% of the 186,767 people who have ever been ranked in the event, and 606th in Canada. Until February 2008, no official 2×2 solve in the world had been that fast. Across 12 competitions since April 2023, he has put 125 official solves on the record across five events. Solve to solve, his 3×3 times vary about 17% around a typical one; 94% of the 35,811 competitors with ten or more counted rounds hold a tighter spread. His 3×3 best has come down from 20.09 in April 2023 to 15.10, a 25% improvement. Leon has entered twelve competitions, more competitions than 94% 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.
