Miron Koolhaas has been competing for 4 years. His best event is the 3×3: a personal-best single of 10.53, set at Amsterdam Open 2023, puts him in the top 9.0% of the 284,439 people who have ever been ranked in the event, and 254th in the Netherlands. Until August 2006, no official 3×3 solve in the world had been that fast. Across 19 competitions since April 2022, he has put 476 official solves on the record across six events.

His 3×3 best has come down from 19.72 in April 2022 to 10.53, a 47% improvement. Miron has entered 19 competitions, more competitions than 97% 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.
