3×3 · top 4.0% of 284,439 all-time · competing since March 2024 · 2024SUGI03
Mitsuki Sugiura (杉浦光紀) has been competing for 2 years. His best event is the 3×3: a personal-best single of 8.61, set at Tokai Summer 2025, puts him in the top 4.0% of the 284,439 people who have ever been ranked in the event, and 168th in Japan. Until July 2008, no official 3×3 solve in the world had been that fast. Across 5 competitions since March 2024, he has put 50 official solves on the record across three events. Solve to solve, his 3×3 times vary about 13% around a typical one, an early reading from 5 counted rounds. His 3×3 best has come down from 12.17 in March 2024 to 8.61, a 29% improvement. Mitsuki has entered five competitions, more competitions than 83% of everyone who has ever competed.

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.
