Ke Sun (孙珂) has been competing for 15 years. His best event is the Pyraminx: a personal-best single of 4.00, set at Zhengzhou Spring Open 2013, puts him in the top 7.6% of the 129,321 people who have ever been ranked in the event, and 902nd in China. Until February 2008, no official Pyraminx solve in the world had been that fast. Across 7 competitions since June 2011, he has put 250 official solves on the record across nine events. Solve to solve, his 3×3 times vary about 10% around a typical one, steadier than 96% of the 35,811 competitors with ten or more counted rounds. His 3×3 best has come down from 12.47 in June 2011 to 10.21, an 18% improvement. Ke has entered seven competitions, more competitions than 88% 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.
