Yexin Cai (蔡烨欣) has been competing for 9 years. Her best event is the 3×3: a personal-best single of 7.56, set at Shantou Open 2018, puts her in the top 2.1% of the 284,439 people who have ever been ranked in the event, and 749th in China. Until July 2008, no official 3×3 solve in the world had been that fast. Across 10 competitions since August 2017, she has put 539 official solves on the record across eight events. Solve to solve, her 3×3 times vary about 13% around a typical one, steadier than 57% of the 35,811 competitors with ten or more counted rounds. Her 3×3 best has come down from 9.98 in August 2017 to 7.56, a 24% improvement. Yexin has entered ten competitions, more competitions than 92% of everyone who has ever competed.

The story so far

Competitions

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.
