Zihao Zhou (周子皓)

3×3 · top 6.7% of 284,439 all-time · competing since July 2012 · 2012ZHOU08

Zihao Zhou (周子皓) has been competing for 14 years. His best event is the 3×3: a personal-best single of 9.72, set at Wuhu Open 2018, puts him in the top 6.7% of the 284,439 people who have ever been ranked in the event, and 2,597th in China. Until November 2007, no official 3×3 solve in the world had been that fast. Across 10 competitions since July 2012, he has put 148 official solves on the record across five events. Solve to solve, his 3×3 times vary about 11% around a typical one, steadier than 87% 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 24.11 in July 2012 to 9.72, a 60% improvement. Zihao has entered ten competitions, more competitions than 92% of everyone who has ever competed.

The story so far

Competitions

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.
