Sihua Guo (郭思桦) has been competing for 2 years. Her best event is the 3×3: a personal-best single of 8.69, set at Beihai Open 2026, puts her in the top 4.2% of the 284,439 people who have ever been ranked in the event, and 1,582nd in China. Until July 2008, no official 3×3 solve in the world had been that fast. Across 4 competitions since July 2024, she has put 83 official solves on the record across four events. Solve to solve, her 3×3 times vary about 13% around a typical one, an early reading from 5 counted rounds. Her 3×3 best has come down from 16.62 in July 2024 to 8.69, a 48% improvement. Sihua has entered four competitions, more competitions than 78% 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.
