Rui Ma (马睿) has been competing for 9 years. His best event is the Skewb: a personal-best single of 2.06, set at China Championship 2018, puts him in the top 1.5% of the 73,281 people who have ever been ranked in the event, and 70th in China. Until December 2014, no official Skewb solve in the world had been that fast. Across 17 competitions since August 2017, he has put 383 official solves on the record across six events. Solve to solve, his 3×3 times vary about 13% around a typical one; 53% of the 35,811 competitors with ten or more counted rounds hold a tighter spread. His Skewb best has come down from 4.20 in August 2017 to 2.06, a 51% improvement. Rui has entered 17 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.
