José Marco Tarifa Hernández

Skewb · top 7.3% of 73,281 all-time · competing since May 2015 · 2015HERN08

José Marco Tarifa Hernández has been competing for 11 years. His best event is the Skewb: a personal-best single of 3.44, set at DiabloRubik 2017, puts him in the top 7.3% of the 73,281 people who have ever been ranked in the event, and 23rd in Bolivia. Until February 2014, no official Skewb solve in the world had been that fast. Across 14 competitions since May 2015, he has put 654 official solves on the record across eleven events. Solve to solve, his 3×3 times vary about 11% around a typical one, steadier than 83% of the 35,811 competitors with ten or more counted rounds. That figure sets aside his 18 DNFs. His 3×3 best has come down from 23.15 in May 2015 to 9.99, a 57% improvement. He has entered 14 competitions, more competitions than 95% of everyone who has ever competed.

Best single per competition, 3×3. 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.
