Yifan Sun (孙逸凡) has been competing for 10 years. His best event is the Pyraminx: a personal-best single of 3.86, set at China Championship 2019, puts him in the top 7.0% of the 129,321 people who have ever been ranked in the event, and 830th in China. Until February 2008, no official Pyraminx solve in the world had been that fast. Across 10 competitions since November 2016, he has put 134 official solves on the record across eight events. Solve to solve, his 3×3 times vary about 12% around a typical one, steadier than 68% of the 35,811 competitors with ten or more counted rounds. His 3×3 best has come down from 44.10 in November 2016 to 12.43, a 72% improvement. Yifan has entered ten competitions, more competitions than 92% 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.
