Muhammad Dzaki Dzulhannan Riandra has been competing for 3 years. His best event is the Pyraminx: a personal-best single of 2.34, set at Balam Cubes Bekasi Comeback 2026, puts him in the top 1.8% of the 130,891 people who have ever been ranked in the event, and 25th in Indonesia. Until July 2011, no official Pyraminx solve in the world had been that fast. Across 18 competitions since February 2024, he has put 445 official solves on the record across seven events. Solve to solve, his 3×3 times vary about 13% around a typical one, steadier than 58% of the 36,406 competitors with ten or more counted rounds. His 3×3 best has come down from 15.97 in February 2024 to 8.42, a 47% improvement. Muhammad has entered 18 competitions, more competitions than 96% 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.
