3×3 · top 3.0% of 284,439 all-time · competing since April 2018 · 2018SUNY02
Yuchang Sun (孙雨畅) has been competing for 8 years. Her best event is the 3×3: a personal-best single of 8.10, set at Tianjin Summer Solstice 2021, puts her in the top 3.0% of the 284,439 people who have ever been ranked in the event, and 1,073rd in China. Until July 2008, no official 3×3 solve in the world had been that fast. Across 6 competitions since April 2018, she has put 58 official solves on the record across two events. Solve to solve, her 3×3 times vary about 10% around a typical one, an early reading from 9 counted rounds. Her 3×3 best has come down from 42.26 in April 2018 to 8.10, an 81% improvement. Yuchang has entered six competitions, more competitions than 86% 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.
