Jashua Chang (郑佳华) has been competing for 9 years. His best event is the 3×3: a personal-best single of 9.90, set at Taipei Winter Open 2018, puts him in the top 7.2% of the 284,439 people who have ever been ranked in the event, and 359th in Malaysia. Until May 2007, no official 3×3 solve in the world had been that fast. Across 3 competitions since December 2017, he has put 72 official solves on the record across six events.

Jashua has entered three competitions, more competitions than 69% 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.
