Shiyuan Ji (籍世源) has been competing for 10 years. His best event is the Pyraminx: a personal-best single of 2.78, set at Auckland Spring 2018, puts him in the top 2.9% of the 129,321 people who have ever been ranked in the event, and 345th in China. Until October 2010, no official Pyraminx solve in the world had been that fast. Across 9 competitions since December 2016, he has put 399 official solves on the record across seven events. Solve to solve, his 3×3 times vary about 13% around a typical one; 56% of the 35,811 competitors with ten or more counted rounds hold a tighter spread. His Pyraminx best has come down from 5.27 in December 2016 to 2.78, a 47% improvement. Shiyuan has entered nine competitions, more competitions than 91% 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.
