Isaac Katz has been competing for 13 years. His best event is the 3×3: a personal-best single of 9.32, set at Hudson Valley Winter 2019, puts him in the top 5.6% of the 284,439 people who have ever been ranked in the event, and 3,142nd in the United States. Until February 2008, no official 3×3 solve in the world had been that fast. Across 3 competitions since October 2013, he has put 53 official solves on the record across five events. Solve to solve, his 3×3 times vary about 14% around a typical one, an early reading from 5 counted rounds. His 3×3 best has come down from 14.84 in October 2013 to 9.32, a 37% improvement. Isaac has entered three competitions, more competitions than 69% 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.
