Ibuki Mio (美尾伊吹) has been competing for 14 years. His best event is the 3×3: a personal-best single of 10.17, set at Japan Open 2017, puts him in the top 8.0% of the 284,439 people who have ever been ranked in the event, and 342nd in Japan. Until May 2007, no official 3×3 solve in the world had been that fast. Across 20 competitions since August 2012, he has put 262 official solves on the record across five events. Solve to solve, his 3×3 times vary about 12% around a typical one, steadier than 79% of the 35,811 competitors with ten or more counted rounds. His 3×3 best has come down from 29.75 in August 2012 to 10.17, a 66% improvement. Ibuki has entered 20 competitions, more competitions than 97% 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.
