Pyraminx · top 9.6% of 129,321 all-time · competing since May 2009 · 2009TANX01

Xiao Tan (谭啸) has been competing for 17 years. His best event is the Pyraminx: a personal-best single of 4.38, set at Beijing Summer Open 2011, puts him in the top 9.6% of the 129,321 people who have ever been ranked in the event, and 1,137th in China. Until September 2006, no official Pyraminx solve in the world had been that fast. Across 11 competitions since May 2009, he has put 232 official solves on the record across six events. Solve to solve, his 3×3 times vary about 12% around a typical one, steadier than 66% of the 35,811 competitors with ten or more counted rounds. His 3×3 best has come down from 25.36 in May 2009 to 14.18, a 44% improvement. Xiao has entered eleven competitions, more competitions than 93% 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.
