Siyi He (何思仪) has been competing for 9 years. Her best event is the Skewb: a personal-best single of 2.44, set at China Championship 2019, puts her in the top 2.7% of the 73,281 people who have ever been ranked in the event, and 141st in China. Until February 2014, no official Skewb solve in the world had been that fast. Across 6 competitions since April 2017, she has put 231 official solves on the record across six events. Solve to solve, her 3×3 times vary about 12% around a typical one, steadier than 70% of the 35,811 competitors with ten or more counted rounds. Her Skewb best has come down from 3.23 in December 2017 to 2.44, a 24% improvement. Siyi has entered six competitions, more competitions than 86% 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.
