3×3 · top 8.9% of 284,439 all-time · competing since August 2019 · 2019LINB03
Bob Lin has been competing for 7 years. His best event is the 3×3: a personal-best single of 10.49, set at Cozy Cubing Poway 2023, puts him in the top 8.9% of the 284,439 people who have ever been ranked in the event, and 3,492nd in China. Until August 2006, no official 3×3 solve in the world had been that fast. Across 7 competitions since August 2019, he has put 63 official solves on the record across three events. Solve to solve, his 3×3 times vary about 15% around a typical one; 80% of the 35,811 competitors with ten or more counted rounds hold a tighter spread. His 3×3 best has come down from 21.53 in August 2019 to 10.49, a 51% improvement. Bob has entered seven competitions, more competitions than 88% 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.
