Ruilin Liu (刘锐霖)
Skewb · top 7.2% of 74,164 all-time · competing since November 2015 · 2015LIUR02
Ruilin Liu (刘锐霖) has been competing for 11 years. His best event is the Skewb: a personal-best single of 3.41, set at Yangzhou Open 2017, puts him in the top 7.2% of the 74,164 people who have ever been ranked in the event, and 402nd in China. Until February 2014, no official Skewb solve in the world had been that fast. Across 6 competitions since November 2015, he has put 178 official solves on the record across five events. Solve to solve, his 3×3 times vary about 13% around a typical one, steadier than 54% of the 36,406 competitors with ten or more counted rounds. That figure sets aside his 3 DNFs. His Skewb best has come down from 7.59 in November 2015 to 3.41, a 55% improvement. Ruilin has entered six competitions, more competitions than 86% 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.
