Blake Koski has been competing for 4 years. His best event is the Square-1: a personal-best single of 8.94, set at Bellevue Squan Fest 2 2024, puts him in the top 4.4% of the 25,662 people who have ever been ranked in the event, and 334th in the United States.

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.
