Yuki Uchida (内田佑毅) has been competing for 12 years. His best event is the Pyraminx: a personal-best single of 2.41, set at Japan Championship 2019, puts him in the top 2.0% of the 129,321 people who have ever been ranked in the event, and 31st in Japan. Until January 2011, no official Pyraminx solve in the world had been that fast. Across 41 competitions since March 2015, he has put 899 official solves on the record across seven events. Solve to solve, his 3×3 times vary about 12% around a typical one, steadier than 61% of the 35,811 competitors with ten or more counted rounds. His 3×3 best has come down from 17.52 in March 2015 to 9.14, a 48% improvement. Yuki has entered 41 competitions, more competitions than 99% 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.
