Guoqin Liu (刘国钦)
3×3 one-handed · top 0.68% of 74,621 all-time · competing since April 2017 · 2017LIUG02
Guoqin Liu (刘国钦) has been competing for 10 years. His best event is the 3×3 one-handed: a personal-best single of 9.37, set at Guangdong Open - Revival & Rival 2026, puts him in the top 0.68% of the 74,621 people who have ever been ranked in the event, and 60th in China. Until November 2013, no official 3×3 one-handed 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 36,406 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.
