Yu Nakajima (中島悠) has been competing for 19 years. His best event is the 2×2: a personal-best single of 1.08, set at Japan Contest 2012, puts him in the top 0.72% of the 186,767 people who have ever been ranked in the event, and 5th in Japan. Until November 2008, no official 2×2 solve in the world had been that fast. Across 74 competitions since July 2007, he has put 2,324 official solves on the record across 17 events. Solve to solve, his 3×3 times vary about 13% around a typical one, steadier than 55% of the 35,811 competitors with ten or more counted rounds. His 3×3 best has come down from 12.21 in July 2007 to 7.00, a 43% improvement. Yu has entered 74 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.
