Mengchen Guo (郭梦宸) has been competing for 1 month. Her best event is the Clock: a personal-best single of 4.91, set at Fuzhou Special 2026, puts her in the top 4.2% of the 32,048 people who have ever been ranked in the event, and 76th in China. Until April 2015, no official Clock solve in the world had been that fast. Across 1 competition since August 2026, she has put 14 official solves on the record across two events.

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.
