Andy Tsao has been competing for 20 years. His best event is the 3×3: a personal-best single of 8.15, set at MIT Fall 2014, puts him in the top 3.1% of the 284,439 people who have ever been ranked in the event, and 1,730th in the United States. Until July 2008, no official 3×3 solve in the world had been that fast. Across 32 competitions since November 2006, he has put 1,234 official solves on the record across eleven events.

His 3×3 best has come down from 14.12 in November 2006 to 8.15, a 42% improvement. Andy has entered 32 competitions, more competitions than 98% of everyone who has ever competed.

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.
