Chang Jiah Zhe has been competing for 7 years. His best event is the 3×3: a personal-best single of 9.37, set at Malaysia Cube Championship 2019, puts him in the top 5.8% of the 284,439 people who have ever been ranked in the event, and 287th in Malaysia. Until February 2008, no official 3×3 solve in the world had been that fast. Across 4 competitions since June 2019, he has put 85 official solves on the record across five events.

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.
