Guoqin Liu (刘国钦)
4×4 · top 0.67% of 83,917 all-time · competing since April 2017 · 2017LIUG02
Guoqin Liu (刘国钦) has been competing for 9 years. His best event is the 4×4: a personal-best single of 24.88, set at Guangzhou Big Cubes 2024, puts him in the top 0.67% of the 83,917 people who have ever been ranked in the event, and 62nd in China. Until January 2014, no official 4×4 solve in the world had been that fast. Across 12 competitions since April 2017, he has put 364 official solves on the record across twelve events. Solve to solve, his 3×3 times vary about 11% around a typical one, steadier than 90% of the 35,811 competitors with ten or more counted rounds. That figure sets aside his 8 DNFs. His 3×3 best has come down from 16.40 in April 2017 to 7.00, a 57% improvement. Guoqin has entered twelve competitions, more competitions than 94% 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.
