Muhammad Za'im Bin Zamzam has been competing for 18 years. His best event is the 3×3: a personal-best single of 9.41, set at Singapore Open 2012, puts him in the top 5.9% of the 284,439 people who have ever been ranked in the event, and 160th in Singapore. Until February 2008, no official 3×3 solve in the world had been that fast. Across 11 competitions since February 2009, he has put 115 official solves on the record across four events. Solve to solve, his 3×3 times vary about 14% around a typical one; 65% of the 35,811 competitors with ten or more counted rounds hold a tighter spread. His 3×3 best has come down from 36.43 in February 2009 to 9.41, a 74% improvement. Muhammad has entered eleven competitions, more competitions than 93% 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.
