Skewb · top 3.5% of 73,281 all-time · competing since October 2016 · 2016KOST03

Kasper Koster has been competing for 10 years. His best event is the Skewb: a personal-best single of 2.67, set at Dutch Nationals 2019, puts him in the top 3.5% of the 73,281 people who have ever been ranked in the event, and 34th in the Netherlands. Until February 2014, no official Skewb solve in the world had been that fast. Across 26 competitions since October 2016, he has put 772 official solves on the record across eleven events. Solve to solve, his 3×3 times vary about 12% around a typical one, steadier than 67% of the 35,811 competitors with ten or more counted rounds. His 3×3 best has come down from 31.38 in October 2016 to 9.57, a 70% improvement. Kasper has entered 26 competitions, more competitions than 98% 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.
