Ruilin Ma (马瑞麟) has been competing for 6 years. His best event is the 3×3: a personal-best single of 9.13, set at Guangzhou Panyu Afternoon 2021, puts him in the top 5.2% of the 284,439 people who have ever been ranked in the event, and 1,969th in China. Until May 2008, no official 3×3 solve in the world had been that fast. Across 5 competitions since December 2020, he has put 45 official solves on the record across one event. Solve to solve, his 3×3 times vary about 10% around a typical one, an early reading from 9 counted rounds. His 3×3 best has come down from 11.14 in December 2020 to 9.13, an 18% improvement. Ruilin has entered five competitions, more competitions than 83% of everyone who has ever competed.

The story so far

Competitions

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.
