2×2 · top 6.6% of 189,179 all-time · competing since January 2021 · 2021OBRI01
Isaac O'Brien has been competing for 6 years. His best event is the 2×2: a personal-best single of 2.24, set at Wonderful Williamstown 2022, puts him in the top 6.6% of the 189,179 people who have ever been ranked in the event, and 505th in Australia. Until February 2008, no official 2×2 solve in the world had been that fast. Across 11 competitions since January 2021, he has put 180 official solves on the record across six events. Solve to solve, his 3×3 times vary about 16% around a typical one; 90% of the 36,406 competitors with ten or more counted rounds hold a tighter spread. His 2×2 best has come down from 7.34 in April 2021 to 2.24, a 69% improvement. Isaac has entered eleven competitions, more competitions than 93% 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.
