Aoqiu Liu (刘澳秋)
Square-1 · top 8.4% of 25,272 all-time · competing since July 2013 · 2013LIUA01
Aoqiu Liu (刘澳秋) has been competing for 13 years. His best event is the Square-1: a personal-best single of 11.25, set at Huizhou Open 2018, puts him in the top 8.4% of the 25,272 people who have ever been ranked in the event, and 125th in China. Until October 2009, no official Square-1 solve in the world had been that fast. Across 11 competitions since July 2013, he has put 152 official solves on the record across six events. Solve to solve, his 3×3 times vary about 11% around a typical one, an early reading from 8 counted rounds. That figure sets aside his 3 DNFs. His Square-1 best has come down from 35.01 in July 2013 to 11.25, a 68% improvement. Aoqiu 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.
