3×3 · top 5.8% of 284,439 all-time · competing since September 2017 · 2017MEJI09

Jafeth Leiva Mejía has been competing for 9 years. His best event is the 3×3: a personal-best single of 9.39, set at Nacionales El Salvador 2018, puts him in the top 5.8% of the 284,439 people who have ever been ranked in the event, and 27th in Costa Rica. Until February 2008, no official 3×3 solve in the world had been that fast. Across 8 competitions since September 2017, he has put 260 official solves on the record across six events. Solve to solve, his 3×3 times vary about 13% around a typical one, steadier than 58% of the 35,811 competitors with ten or more counted rounds. His 3×3 best has come down from 12.06 in September 2017 to 9.39, a 22% improvement. Jafeth has entered eight competitions, more competitions than 90% 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.
