Jim Chan
3×3 · top 5.4% of 284,439 all-time · competing since May 2018 · 2018CHAN29
Jim Chan has been competing for 8 years. His best event is the 3×3: a personal-best single of 9.24, set at UMass Spring 2026, puts him in the top 5.4% of the 284,439 people who have ever been ranked in the event, and 3,042nd in the United States. Until February 2008, no official 3×3 solve in the world had been that fast. Across 8 competitions since May 2018, he has put 209 official solves on the record across nine events. Solve to solve, his 3×3 times vary about 9% around a typical one, steadier than 98% of the 35,811 competitors with ten or more counted rounds. That figure sets aside his 4 DNFs. His 3×3 best has come down from 24.51 in May 2018 to 9.24, a 62% improvement. Jim has entered eight competitions, more competitions than 90% 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.
