Ma Ching Hei (馬正希) has been competing for 7 years. His best event is the 2×2: a personal-best single of 1.24, set at HKRCU 20th Anniversary 2025, puts him in the top 1.2% of the 189,179 people who have ever been ranked in the event, and 18th in Hong Kong, China. Until November 2008, no official 2×2 solve in the world had been that fast. Across 3 competitions since August 2019, he has put 95 official solves on the record across four events.

Ma 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.
