Jianheng Qiu (邱健恒)
3×3 · top 8.8% of 284,439 all-time · competing since July 2010 · 2010QIUJ01
Jianheng Qiu (邱健恒) has been competing for 16 years. His best event is the 3×3: a personal-best single of 10.44, set at Guangdong Open 2014, puts him in the top 8.8% of the 284,439 people who have ever been ranked in the event, and 3,419th in China. Until February 2007, no official 3×3 solve in the world had been that fast. Across 8 competitions since July 2010, he has put 160 official solves on the record across six events. Solve to solve, his 3×3 times vary about 14% around a typical one, an early reading from 6 counted rounds. That figure sets aside his 3 DNFs. His 2×2 best has come down from 4.96 in October 2010 to 4.40, an 11% improvement. Jianheng has entered eight competitions, more competitions than 90% 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.
