Yifan Chen (陈一凡) has been competing for 7 years. His best event is the Skewb: a personal-best single of 1.49, set at Hangzhou Open PM 2021, puts him in the top 0.44% of the 73,281 people who have ever been ranked in the event, and 26th in China. Until October 2015, no official Skewb solve in the world had been that fast. Across 5 competitions since November 2019, he has put 96 official solves on the record across five events. Solve to solve, his 3×3 times vary about 13% around a typical one, an early reading from 8 counted rounds. His 3×3 best has come down from 12.48 in November 2019 to 8.31, a 33% improvement. Yifan has entered five competitions, more competitions than 83% 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.
