Zirui Liu (刘子瑞) has been competing for 9 years. His best event is the 3×3: a personal-best single of 10.05, set at Guangdong Open 2021, puts him in the top 7.6% of the 284,439 people who have ever been ranked in the event, and 2,970th in China. Until May 2007, no official 3×3 solve in the world had been that fast. Across 6 competitions since October 2017, he has put 169 official solves on the record across five events. Solve to solve, his 3×3 times vary about 8% around a typical one, steadier than 99% of the 35,811 competitors with ten or more counted rounds. His 3×3 best has come down from 11.26 in October 2017 to 10.05, an 11% improvement. Zirui 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.
