Harrison Brock has been competing for 4 years. His best event is the 2×2: a personal-best single of 2.12, set at Atlanta Algs at AIS Autumn 2025, puts him in the top 5.6% of the 186,767 people who have ever been ranked in the event, and 2,232nd in the United States. Until February 2008, no official 2×2 solve in the world had been that fast. Across 5 competitions since November 2022, he has put 90 official solves on the record across three events.

His 3×3 best has come down from 14.33 in November 2022 to 10.27, a 28% improvement. Harrison has entered five competitions, more competitions than 83% 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.
