Kai Mochida

3×3 · top 5.9% of 284,439 all-time · competing since October 2020 · 2020MOCH02

Kai Mochida has been competing for 6 years. His best event is the 3×3: a personal-best single of 9.44, set at A New Year in Hamilton 2023, puts him in the top 5.9% of the 284,439 people who have ever been ranked in the event, and 250th in Japan. Until February 2008, no official 3×3 solve in the world had been that fast. Across 5 competitions since October 2020, he has put 141 official solves on the record across five events. Solve to solve, his 3×3 times vary about 12% around a typical one, steadier than 75% of the 35,811 competitors with ten or more counted rounds. His 3×3 best has come down from 16.23 in October 2020 to 9.44, a 42% improvement. Kai has entered five competitions, more competitions than 83% 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.
