Ruicheng Li (李睿成)
3×3 · top 5.0% of 284,439 all-time · competing since July 2015 · 2015LIRU02
Ruicheng Li (李睿成) has been competing for 11 years. His best event is the 3×3: a personal-best single of 9.05, set at Zhongshan Children's Cube Day 2019, puts him in the top 5.0% of the 284,439 people who have ever been ranked in the event, and 1,895th in China. Until May 2008, no official 3×3 solve in the world had been that fast. Across 23 competitions since July 2015, he has put 328 official solves on the record across three events. Solve to solve, his 3×3 times vary about 12% around a typical one, steadier than 64% of the 35,811 competitors with ten or more counted rounds. His 3×3 best has come down from 14.90 in July 2015 to 9.05, a 39% improvement. Ruicheng has entered 23 competitions, more competitions than 97% 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.
