Yen-Chen Chiang (江彥辰) has been competing for 14 years. His best event is the 4×4: a personal-best single of 36.39, set at Zurich Open 2019, puts him in the top 8.1% of the 85,040 people who have ever been ranked in the event, and 200th in Chinese Taipei. Until July 2010, no official 4×4 solve in the world had been that fast. Across 6 competitions since August 2012, he has put 110 official solves on the record across five events. Solve to solve, his 3×3 times vary about 10% around a typical one, an early reading from 9 counted rounds. His 3×3 best has come down from 13.37 in August 2012 to 10.84, a 19% improvement. He 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.
