Jie Ma (马杰) has been competing for 11 years. His best event is the 2×2: a personal-best single of 2.10, set at Zhengzhou Summer 2021, puts him in the top 5.4% of the 186,767 people who have ever been ranked in the event, and 758th in China. Until February 2008, no official 2×2 solve in the world had been that fast. Across 16 competitions since May 2015, he has put 366 official solves on the record across eight events. Solve to solve, his 3×3 times vary about 13% around a typical one, steadier than 53% of the 35,811 competitors with ten or more counted rounds. His 3×3 best has come down from 20.19 in May 2015 to 14.54, a 28% improvement. Jie has entered 16 competitions, more competitions than 96% 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.
