Chang Heh Waah Aethan has been competing for 3 years. His best event is the 2×2: a personal-best single of 1.85, set at Mofunland Speedcubing Singapore 2024, puts him in the top 3.9% of the 189,179 people who have ever been ranked in the event, and 73rd in Singapore. Until February 2008, no official 2×2 solve in the world had been that fast. Across 5 competitions since September 2023, he has put 78 official solves on the record across seven 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.
