3×3 blindfolded · top 3.0% of 12,178 all-time · competing since December 2018 · 2018TAIR02

Keiichiro Taira (平佳一郎) has been competing for 8 years. His best event is the 3×3 blindfolded: a personal-best single of 25.32, set at Ota Blind Summer 2022, puts him in the top 3.0% of the 12,178 people who have ever been ranked in the event, and 14th in Japan. Until June 2013, no official 3×3 blindfolded solve in the world had been that fast. Across 23 competitions since December 2018, he has put 257 official solves on the record across 17 events. Solve to solve, his 3×3 times vary about 11% around a typical one, steadier than 82% of the 35,811 competitors with ten or more counted rounds. His 3×3 best has come down from 14.63 in December 2018 to 9.03, a 38% improvement. Keiichiro has entered 23 competitions, more competitions than 97% 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.
