Jack Osorio Herrera

Skewb · top 7.5% of 73,281 all-time · competing since April 2017 · 2017HERR08

Jack Osorio Herrera has been competing for 9 years. His best event is the Skewb: a personal-best single of 3.47, set at Aventura Cúbica V 2018, puts him in the top 7.5% of the 73,281 people who have ever been ranked in the event, and 60th in Peru. Until February 2014, no official Skewb solve in the world had been that fast. Across 8 competitions since April 2017, he has put 138 official solves on the record across five events. Solve to solve, his 3×3 times vary about 12% around a typical one, an early reading from 9 counted rounds. His 3×3 best has come down from 20.96 in April 2017 to 13.52, a 35% improvement. Jack has entered eight competitions, more competitions than 90% 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.
