Chengda Ge (葛成达) has been competing for 10 years. His best event is the Skewb: a personal-best single of 2.20, set at Shenyang New Year 2019, puts him in the top 1.9% of the 73,281 people who have ever been ranked in the event, and 92nd in China. Until February 2014, no official Skewb solve in the world had been that fast. Across 13 competitions since December 2016, he has put 286 official solves on the record across six events. Solve to solve, his 3×3 times vary about 9% around a typical one, steadier than 99% of the 35,811 competitors with ten or more counted rounds. His Skewb best has come down from 5.95 in December 2016 to 2.20, a 63% improvement. Chengda has entered 13 competitions, more competitions than 94% 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.
