Alvin Robertsson
Pyraminx · top 8.6% of 130,891 all-time · competing since May 2016 · 2016ROBE05
Alvin Robertsson has been competing for 10 years. His best event is the Pyraminx: a personal-best single of 4.18, set at SSL 1 Jönköping 2017, puts him in the top 8.6% of the 130,891 people who have ever been ranked in the event, and 203rd in Sweden. Until September 2006, no official Pyraminx solve in the world had been that fast. Across 6 competitions since May 2016, he has put 137 official solves on the record across eight events. Solve to solve, his 3×3 times vary about 16% around a typical one, an early reading from 6 counted rounds. That figure sets aside his 2 DNFs. His Pyraminx best has come down from 15.65 in May 2016 to 4.18, a 73% improvement. Alvin 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.
