Huaiyi Liu (刘怀熠) has been competing for 9 years. His best event is the Pyraminx: a personal-best single of 2.65, set at Changsha Spring Open 2019, puts him in the top 2.6% of the 129,321 people who have ever been ranked in the event, and 306th in China. Until October 2010, no official Pyraminx solve in the world had been that fast. Across 8 competitions since May 2017, he has put 182 official solves on the record across eight events. Solve to solve, his 3×3 times vary about 12% around a typical one, steadier than 81% of the 35,811 competitors with ten or more counted rounds. His 3×3 best has come down from 17.47 in May 2017 to 13.39, a 23% improvement. Huaiyi 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.
