Zihan Guo (郭子涵) has been competing for 10 years. Her best event is the 3×3: a personal-best single of 10.04, set at Dongguan Open 2019, puts her in the top 7.6% of the 284,439 people who have ever been ranked in the event, and 2,954th in China. Until May 2007, no official 3×3 solve in the world had been that fast. Across 16 competitions since April 2016, she has put 156 official solves on the record across one event. Solve to solve, her 3×3 times vary about 13% around a typical one, steadier than 56% of the 35,811 competitors with ten or more counted rounds. Her 3×3 best has come down from 21.66 in April 2016 to 10.04, a 54% improvement. Zihan has entered 16 competitions, more competitions than 96% 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.
