Aya Ishikura (石倉文)

Megaminx · top 7.4% of 34,786 all-time · competing since November 2014 · 2014AKAB01

Aya Ishikura (石倉文) has been competing for 12 years. Her best event is the Megaminx: a personal-best single of 54.81, set at Hiroshima Spring 2023, puts her in the top 7.4% of the 34,786 people who have ever been ranked in the event, and 56th in Japan. Until April 2010, no official Megaminx solve in the world had been that fast. Across 17 competitions since November 2014, she has put 131 official solves on the record across five events. Solve to solve, her 3×3 times vary about 11% around a typical one, steadier than 83% of the 35,811 competitors with ten or more counted rounds. Her 3×3 best has come down from 26.80 in November 2014 to 11.99, a 55% improvement. Aya has entered 17 competitions, more competitions than 96% 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.
