Tatsuhiro Ito (伊藤龍弘) has been competing for 19 years. His best event is the Pyraminx: a personal-best single of 2.59, set at Tokyo Pyraminx Open 2017, puts him in the top 2.4% of the 129,321 people who have ever been ranked in the event, and 36th in Japan. Until January 2011, no official Pyraminx solve in the world had been that fast. Across 10 competitions since July 2007, he has put 132 official solves on the record across five events.

His 3×3 best has come down from 38.33 in July 2007 to 12.65, a 67% improvement. Tatsuhiro has entered ten competitions, more competitions than 92% 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.
