Jie-Ju Chen (陳玠儒) has been competing for 17 years. His best event is the 3×3: a personal-best single of 10.46, set at Cubik Box Cup 2011, puts him in the top 8.8% of the 284,439 people who have ever been ranked in the event, and 526th in Chinese Taipei. Until February 2007, no official 3×3 solve in the world had been that fast. Across 6 competitions since May 2009, he has put 121 official solves on the record across seven events.

His 3×3 best has come down from 12.34 in May 2009 to 10.46, a 15% 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.
