Zhitian Chen (陈知湉) has been competing for 7 years. Her best event is the 3×3: a personal-best single of 8.70, set at Beijing Spring AM 2021, puts her in the top 4.2% of the 284,439 people who have ever been ranked in the event, and 1,591st in China. Until July 2008, no official 3×3 solve in the world had been that fast. Across 5 competitions since December 2019, she has put 44 official solves on the record across two events. Solve to solve, her 3×3 times vary about 8% around a typical one, an early reading from 7 counted rounds. Her 3×3 best has come down from 17.59 in December 2019 to 8.70, a 51% improvement. Zhitian has entered five competitions, more competitions than 83% 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.
