Isaac Jeffries
Pyraminx · top 4.0% of 129,321 all-time · competing since April 2025 · 2025JEFF03
Isaac Jeffries has been competing for a year. His best event is the Pyraminx: a personal-best single of 3.11, set at Wiltshire Summer 2026, puts him in the top 4.0% of the 129,321 people who have ever been ranked in the event, and 165th in the United Kingdom. Until February 2008, no official Pyraminx solve in the world had been that fast. Across 8 competitions since April 2025, he has put 391 official solves on the record across 13 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. That figure sets aside his 6 DNFs. His 3×3 best has come down from 19.94 in April 2025 to 9.94, a 50% improvement. Isaac has entered eight competitions, more competitions than 90% 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.
