2×2 · top 7.8% of 186,767 all-time · competing since October 2016 · 2016GUOZ04
Ziyang Guo (郭子阳) has been competing for 10 years. His best event is the 2×2: a personal-best single of 2.38, set at Beijing Summer 2025, puts him in the top 7.8% of the 186,767 people who have ever been ranked in the event, and 1,121st in China. Until February 2008, no official 2×2 solve in the world had been that fast. Across 6 competitions since October 2016, he has put 139 official solves on the record across six events. Solve to solve, his 3×3 times vary about 10% around a typical one, steadier than 94% of the 35,811 competitors with ten or more counted rounds. His 3×3 best has come down from 14.55 in October 2016 to 10.31, a 29% improvement. Ziyang has entered six competitions, more competitions than 86% 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.
