2×2 · top 1.4% of 186,767 all-time · competing since December 2015 · 2015CRUM04

Cormac Crump has been competing for 11 years. His best event is the 2×2: a personal-best single of 1.31, set at Quabbin Open 2016, puts him in the top 1.4% of the 186,767 people who have ever been ranked in the event, and 576th in the United States. Until November 2008, no official 2×2 solve in the world had been that fast. Across 12 competitions since December 2015, he has put 443 official solves on the record across nine events.

His 3×3 best has come down from 15.16 in December 2015 to 8.10, a 47% improvement. Cormac has entered twelve competitions, more competitions than 94% of everyone who has ever competed.

The story so far

Competitions

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.
