Ryo Kozawa (小澤諒) has been competing for 14 years. His best event is the 3×3 blindfolded: a personal-best single of 45.96, set at Asian Championship 2014, puts him in the top 8.6% of the 12,178 people who have ever been ranked in the event, and 43rd in Japan. Until July 2009, no official 3×3 blindfolded solve in the world had been that fast. Across 17 competitions since August 2012, he has put 215 official solves on the record across nine events. Solve to solve, his 3×3 times vary about 17% around a typical one; 97% of the 35,811 competitors with ten or more counted rounds hold a tighter spread. His 3×3 best has come down from 14.58 in August 2012 to 11.88, a 19% improvement. Ryo has entered 17 competitions, more competitions than 96% 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.
