Pyraminx · top 3.5% of 129,321 all-time · competing since November 2016 · 2016CHES06
Sean Cheng has been competing for 10 years. His best event is the Pyraminx: a personal-best single of 2.97, set at Deerfield Winter 2022, puts him in the top 3.5% of the 129,321 people who have ever been ranked in the event, and 938th in the United States. Until February 2008, no official Pyraminx solve in the world had been that fast. Across 6 competitions since November 2016, he has put 178 official solves on the record across five events. Solve to solve, his 3×3 times vary about 14% around a typical one; 64% of the 35,811 competitors with ten or more counted rounds hold a tighter spread. His 3×3 best has come down from 13.82 in November 2016 to 8.63, a 38% improvement. Sean has entered six competitions, more competitions than 86% 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.
