Daiziro Sato (佐藤大二郎)

3×3 · top 7.1% of 284,439 all-time · competing since March 2009 · 2009SATO01

Daiziro Sato (佐藤大二郎) has been competing for 18 years. His best event is the 3×3: a personal-best single of 9.88, set at Japan Open 2011, puts him in the top 7.1% of the 284,439 people who have ever been ranked in the event, and 309th in Japan. Until May 2007, no official 3×3 solve in the world had been that fast. Across 6 competitions since March 2009, he has put 191 official solves on the record across five events. Solve to solve, his 3×3 times vary about 10% around a typical one, steadier than 98% of the 35,811 competitors with ten or more counted rounds. His 3×3 best has come down from 14.40 in March 2009 to 9.88, a 31% improvement. Daiziro has entered six competitions, more competitions than 86% of everyone who has ever competed.

Best single per competition, 3×3. Faster is higher — the axis is the right way up.

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.
