Jakub Zaczkowski has been competing for 13 years. His best event is the Skewb: a personal-best single of 3.59, set at Santa Claus Cube Race 2014, puts him in the top 8.3% of the 73,281 people who have ever been ranked in the event, and 369th in Poland. Until February 2014, no official Skewb solve in the world had been that fast. Across 14 competitions since October 2013, he has put 396 official solves on the record across six events.

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.
