Sijia Liu (刘思嘉)
3×3 · top 6.4% of 284,439 all-time · competing since January 2018 · 2018LIUS02
Sijia Liu (刘思嘉) has been competing for 9 years. His best event is the 3×3: a personal-best single of 9.63, set at Suzhou Open 2019, puts him in the top 6.4% of the 284,439 people who have ever been ranked in the event, and 2,489th in China. Until November 2007, no official 3×3 solve in the world had been that fast. Across 11 competitions since January 2018, he has put 287 official solves on the record across seven events. Solve to solve, his 3×3 times vary about 14% around a typical one; 63% of the 35,811 competitors with ten or more counted rounds hold a tighter spread. That figure sets aside his 5 DNFs. His 3×3 best has come down from 11.97 in January 2018 to 9.63, a 20% improvement. Sijia 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.
