Boyun Zheng (郑博允) has been competing for 7 years. Her best event is the 3×3: a personal-best single of 10.23, set at Kunshan Morning 2021, puts her in the top 8.1% of the 284,439 people who have ever been ranked in the event, and 3,185th in China. Until May 2007, no official 3×3 solve in the world had been that fast. Across 3 competitions since November 2019, she has put 30 official solves on the record across three events. Her 3×3 best has come down from 19.54 in November 2019 to 10.23, a 48% improvement. Boyun has entered three competitions, more competitions than 69% 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.
