David Alfaro Estrada has been competing for 8 years. His best event is the 3×3: a personal-best single of 9.12, set at Grecia Open 2019, puts him in the top 5.1% of the 284,439 people who have ever been ranked in the event, and 23rd in Costa Rica. Until May 2008, no official 3×3 solve in the world had been that fast. Across 3 competitions since March 2018, he has put 142 official solves on the record across eight events. Solve to solve, his 3×3 times vary about 14% around a typical one, an early reading from 7 counted rounds. That figure sets aside his 2 DNFs. His 3×3 best has come down from 12.77 in March 2018 to 9.12, a 29% improvement. David has entered three competitions, more competitions than 69% 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.
