Zhenkun Liu (刘镇坤) has been competing for 8 years. His best event is the 3×3: a personal-best single of 9.31, set at Wuhan Chuyun Spring 2019, puts him in the top 5.6% of the 284,439 people who have ever been ranked in the event, and 2,168th in China. Until February 2008, no official 3×3 solve in the world had been that fast. Across 3 competitions since December 2018, he has put 47 official solves on the record across three events. Solve to solve, his 3×3 times vary about 13% around a typical one, an early reading from 6 counted rounds. His 3×3 best has come down from 11.74 in December 2018 to 9.31, a 21% improvement. Zhenkun has entered three competitions, more competitions than 69% 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.
