Masahiro Yamakita (山北真大)

Skewb · top 6.4% of 73,281 all-time · competing since September 2015 · 2015YAMA05

Masahiro Yamakita (山北真大) has been competing for 11 years. His best event is the Skewb: a personal-best single of 3.26, set at Kansai Small Cubes 2016, puts him in the top 6.4% of the 73,281 people who have ever been ranked in the event, and 32nd in Japan. Until February 2014, no official Skewb solve in the world had been that fast. Across 13 competitions since September 2015, he has put 127 official solves on the record across four events. Solve to solve, his 3×3 times vary about 16% around a typical one; 93% of the 35,811 competitors with ten or more counted rounds hold a tighter spread. His 3×3 best has come down from 18.68 in September 2015 to 12.91, a 31% improvement. Masahiro has entered 13 competitions, more competitions than 94% 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.
