Muhammad Dzaki Dzulhannan Riandra has been competing for 3 years. His best event is the 2×2: a personal-best single of 1.78, set at Kalibata Agustusan 2026, puts him in the top 3.5% of the 186,767 people who have ever been ranked in the event, and 79th in Indonesia. Until February 2008, no official 2×2 solve in the world had been that fast. Across 15 competitions since February 2024, he has put 340 official solves on the record across five events. Solve to solve, his 3×3 times vary about 14% around a typical one; 63% of the 35,811 competitors with ten or more counted rounds hold a tighter spread. His 3×3 best has come down from 15.97 in February 2024 to 8.73, a 45% improvement. Muhammad has entered 15 competitions, more competitions than 95% 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.
