William Bellerive-Kammann has been competing for a year. His best event is the Pyraminx: a personal-best single of 4.41, set at Ottawa Spring 2026, puts him in the top 9.8% of the 129,321 people who have ever been ranked in the event, and 357th in Canada. Until September 2006, no official Pyraminx solve in the world had been that fast. Across 9 competitions since April 2025, he has put 207 official solves on the record across ten events. Solve to solve, his 3×3 times vary about 10% around a typical one, steadier than 98% of the 35,811 competitors with ten or more counted rounds. His 3×3 best has come down from 21.99 in July 2025 to 15.57, a 29% improvement. William has entered nine competitions, more competitions than 91% 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.
