Juan Andres Bustos Rosales

2×2 · top 1.6% of 186,767 all-time · competing since April 2024 · 2024ROSA07

Juan Andres Bustos Rosales has been competing for 2 years. His best event is the 2×2: a personal-best single of 1.36, set at Unicen Open SCZ 2025, puts him in the top 1.6% of the 186,767 people who have ever been ranked in the event, and 9th in Bolivia. Until November 2008, no official 2×2 solve in the world had been that fast. Across 19 competitions since April 2024, he has put 610 official solves on the record across nine events. Solve to solve, his 3×3 times vary about 16% around a typical one; 89% of the 35,811 competitors with ten or more counted rounds hold a tighter spread. That figure sets aside his 10 DNFs. His 3×3 best has come down from 20.32 in April 2024 to 8.81, a 57% improvement. Juan has entered 19 competitions, more competitions than 97% of everyone who has ever competed.

The story so far

Competitions

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.
