Petr Kundera has been competing for 7 years. His best event is the Skewb: a personal-best single of 2.99, set at Lužice Summer 2023, puts him in the top 5.0% of the 74,164 people who have ever been ranked in the event, and 28th in the Czech Republic. Until February 2014, no official Skewb solve in the world had been that fast. Across 34 competitions since September 2019, he has put 824 official solves on the record across five events.

His Skewb best has come down from 5.65 in August 2021 to 2.99, a 47% improvement. Petr has entered 34 competitions, more competitions than 98% of everyone who has ever competed.

Best single per competition, Skewb. Faster is higher — the axis is the right way up.

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.
