Rex Li has been competing for 7 years. His best event is the 3×3: a personal-best single of 6.31, set at Waterloo Spring 2026, puts him in the top 0.69% of the 284,439 people who have ever been ranked in the event, and 258th in China. Until May 2011, no official 3×3 solve in the world had been that fast. Across 11 competitions since October 2019, he has put 292 official solves on the record across four events. Solve to solve, his 3×3 times vary about 10% around a typical one, steadier than 96% of the 35,811 competitors with ten or more counted rounds. His 3×3 best has come down from 15.13 in October 2019 to 6.31, a 58% improvement. Rex has entered eleven competitions, more competitions than 93% 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.
