Jacob McGruddy has been competing for 10 years. His best event is the 2×2: a personal-best single of 1.42, set at Victorian Open 2022, puts him in the top 1.8% of the 186,767 people who have ever been ranked in the event, and 158th in Australia. Until November 2008, no official 2×2 solve in the world had been that fast. Across 15 competitions since July 2016, he has put 598 official solves on the record across 14 events.

His 3×3 best has come down from 17.63 in July 2016 to 9.22, a 48% improvement. Jacob has entered 15 competitions, more competitions than 95% 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.
