Siyuan Dai (戴思源) has been competing for 10 years. His best event is the Pyraminx: a personal-best single of 4.43, set at Suzhou Open 2017, puts him in the top 9.9% of the 130,891 people who have ever been ranked in the event, and 1,185th in China. Until September 2006, no official Pyraminx solve in the world had been that fast. Across 4 competitions since November 2016, he has put 86 official solves on the record across eight events. Solve to solve, his 3×3 times vary about 17% around a typical one, an early reading from 6 counted rounds. His 3×3 best has come down from 27.20 in November 2016 to 13.10, a 52% improvement. Siyuan has entered four competitions, more competitions than 78% 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.
