Taihei Serizawa (芹澤泰平) has been competing for 14 years. His best event is the 3×3: a personal-best single of 10.56, set at UT Open 2012, puts him in the top 9.1% of the 284,439 people who have ever been ranked in the event, and 400th in Japan. Until August 2006, no official 3×3 solve in the world had been that fast. Across 3 competitions since June 2012, he has put 59 official solves on the record across five events.

Taihei has entered three competitions, more competitions than 69% 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.
