Yirong Chen (陈奕镕)
Pyraminx · top 5.6% of 130,891 all-time · competing since July 2017 · 2017CHEY07
Yirong Chen (陈奕镕) has been competing for 9 years. His best event is the Pyraminx: a personal-best single of 3.54, set at Kunshan Side Events 2021, puts him in the top 5.6% of the 130,891 people who have ever been ranked in the event, and 685th in China. Until February 2008, no official Pyraminx solve in the world had been that fast. Across 9 competitions since July 2017, he has put 134 official solves on the record across four events. Solve to solve, his 3×3 times vary about 15% around a typical one, an early reading from 9 counted rounds. That figure sets aside his 3 DNFs. His Pyraminx best has come down from 11.06 in July 2017 to 3.54, a 68% improvement. Yirong 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.
