Skewb · top 7.7% of 73,281 all-time · competing since June 2015 · 2015CAST07
Marcos Roberto Galvão Castro has been competing for 11 years. His best event is the Skewb: a personal-best single of 3.49, set at 100º Mérito 2018, puts him in the top 7.7% of the 73,281 people who have ever been ranked in the event, and 78th in Brazil. Until February 2014, no official Skewb solve in the world had been that fast. Across 7 competitions since June 2015, he has put 208 official solves on the record across five events. Solve to solve, his 3×3 times vary about 15% around a typical one; 84% of the 35,811 competitors with ten or more counted rounds hold a tighter spread. His 3×3 best has come down from 44.45 in June 2015 to 18.32, a 59% improvement. Marcos has entered seven competitions, more competitions than 88% 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.
