Justin Barber has been competing for 11 years. His best event is the 3×3: a personal-best single of 6.95, set at Berkeley Spring 2016, puts him in the top 1.3% of the 284,439 people who have ever been ranked in the event, and 777th in the United States. Until November 2010, no official 3×3 solve in the world had been that fast. Across 12 competitions since November 2015, he has put 214 official solves on the record across six events.

His 3×3 best has come down from 8.84 in November 2015 to 6.95, a 21% improvement. Justin has entered twelve competitions, more competitions than 94% 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.
