Chenfei Sun (孙晨飞) has been competing for 18 years. His best event is the Pyraminx: a personal-best single of 5.38, set at Beijing No Cubes 2010, puts him in the top 15.6% of the 129,321 people who have ever been ranked in the event, and 1,834th in China. Across 7 competitions since November 2008, he has put 59 official solves on the record across five events. Solve to solve, his 3×3 times vary about 23% around a typical one, an early reading from 5 counted rounds. That figure sets aside his 2 DNFs.

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.
