Shanmeng Dong (董杉萌) has been competing for 10 years. His best event is the Pyraminx: a personal-best single of 4.38, set at Weihai Open 2017, 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 8 competitions since May 2016, he has put 173 official solves on the record across four events.

His Pyraminx best has come down from 11.76 in May 2016 to 4.38, a 63% improvement. Shanmeng has entered eight competitions, more competitions than 90% 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.
