Daniel Buck Silva

2×2 · top 8.9% of 186,767 all-time · competing since July 2012 · 2012SILV10

Daniel Buck Silva has been competing for 14 years. His best event is the 2×2: a personal-best single of 2.50, set at World Rubik's Cube Championship 2015, puts him in the top 8.9% of the 186,767 people who have ever been ranked in the event, and 288th in Brazil. Until February 2008, no official 2×2 solve in the world had been that fast. Across 15 competitions since July 2012, he has put 192 official solves on the record across four events. Solve to solve, his 3×3 times vary about 17% around a typical one; 95% of the 35,811 competitors with ten or more counted rounds hold a tighter spread. His 3×3 best has come down from 48.53 in July 2012 to 14.98, a 69% improvement. Daniel has entered 15 competitions, more competitions than 95% 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.
