Yichen Ma (马奕宸)
Pyraminx · top 2.4% of 129,321 all-time · competing since July 2016 · 2016MAYI03
Yichen Ma (马奕宸) has been competing for 10 years. His best event is the Pyraminx: a personal-best single of 2.58, set at Kunshan Side Events 2021, puts him in the top 2.4% of the 129,321 people who have ever been ranked in the event, and 287th in China. Until January 2011, no official Pyraminx solve in the world had been that fast. Across 11 competitions since July 2016, he has put 123 official solves on the record across five events. Solve to solve, his 3×3 times vary about 13% around a typical one; 55% of the 35,811 competitors with ten or more counted rounds hold a tighter spread. That figure sets aside his 3 DNFs. His 3×3 best has come down from 31.56 in July 2016 to 10.84, a 66% improvement. Yichen has entered eleven competitions, more competitions than 93% 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.
