Yun Zheng (郑允) has been competing for 18 years. His best event is the 3×3: a personal-best single of 13.81, set at Guangdong Open 2009, puts him in the top 20.3% of the 284,439 people who have ever been ranked in the event, and 7,862nd in China. Across 3 competitions since July 2008, he has put 52 official solves on the record across four events. Solve to solve, his 3×3 times vary about 14% around a typical one, an early reading from 5 counted rounds. That figure sets aside his 2 DNFs. His 3×3 best has come down from 16.59 in July 2008 to 13.81, a 17% improvement. Yun 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.
