Pyraminx · top 6.8% of 130,891 all-time · competing since October 2021 · 2021SOND01
David Sønderby has been competing for 5 years. His best event is the Pyraminx: a personal-best single of 3.82, set at Danish Championship 2026, puts him in the top 6.8% of the 130,891 people who have ever been ranked in the event, and 65th in Denmark. Until February 2008, no official Pyraminx solve in the world had been that fast. Across 11 competitions since October 2021, he has put 211 official solves on the record across five events. Solve to solve, his 3×3 times vary about 16% around a typical one; 90% of the 36,406 competitors with ten or more counted rounds hold a tighter spread. His 3×3 best has come down from 36.43 in October 2021 to 13.19, a 64% improvement. David 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.
