William Moulden

Pyraminx · top 7.2% of 129,321 all-time · competing since July 2018 · 2018MOUL03

William Moulden has been competing for 8 years. His best event is the Pyraminx: a personal-best single of 3.90, set at WCA World Championship 2019, puts him in the top 7.2% of the 129,321 people who have ever been ranked in the event, and 320th in Australia. Until February 2008, no official Pyraminx solve in the world had been that fast. Across 7 competitions since July 2018, he has put 242 official solves on the record across ten events. Solve to solve, his 3×3 times vary about 14% around a typical one; 70% of the 35,811 competitors with ten or more counted rounds hold a tighter spread. His 3×3 best has come down from 24.96 in July 2018 to 11.99, a 52% improvement. William has entered seven competitions, more competitions than 88% of everyone who has ever competed.

Best single per competition, 3×3. Faster is higher — the axis is the right way up.

The story so far

Competitions

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.
