Zhigao Cheng (程志高)
4×4 · top 5.0% of 83,917 all-time · competing since November 2012 · 2012CHEN51
Zhigao Cheng (程志高) has been competing for 14 years. His best event is the 4×4: a personal-best single of 33.01, set at Wuhu Open 2018, puts him in the top 5.0% of the 83,917 people who have ever been ranked in the event, and 490th in China. Until November 2010, no official 4×4 solve in the world had been that fast. Across 3 competitions since November 2012, he has put 82 official solves on the record across five events. Solve to solve, his 3×3 times vary about 9% 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 14.74 in November 2012 to 10.22, a 31% improvement. Zhigao 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.
