David Chen
3×3 · top 7.7% of 284,439 all-time · competing since August 2016 · 2016CHED01
David Chen has been competing for 10 years. His best event is the 3×3: a personal-best single of 10.09, set at Waterloo Winter 2025, puts him in the top 7.7% of the 284,439 people who have ever been ranked in the event, and 719th in Canada. Until May 2007, no official 3×3 solve in the world had been that fast. Across 5 competitions since August 2016, he has put 83 official solves on the record across five events. Solve to solve, his 3×3 times vary about 11% around a typical one, steadier than 90% of the 35,811 competitors with ten or more counted rounds. His 3×3 best has come down from 14.98 in August 2016 to 10.09, a 33% improvement. David 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.
