Marianela Fernández Mamani has been competing for 4 years. Her best event is the Pyraminx: a personal-best single of 5.85, set at Chapacos Cuberos 2023, puts her in the top 18.9% of the 129,321 people who have ever been ranked in the event, and 150th in Bolivia. Across 18 competitions since September 2022, she has put 264 official solves on the record across eight events. Solve to solve, her 3×3 times vary about 12% around a typical one, steadier than 67% of the 35,811 competitors with ten or more counted rounds. That figure sets aside her 7 DNFs. Her 3×3 best has come down from 29.56 in September 2022 to 17.62, a 40% improvement. Marianela 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.
