Jefferson Fermin Soto Caballero has been competing for 8 years. His best event is the 3×3: a personal-best single of 10.00, set at SAM Center Open 2024, puts him in the top 7.4% of the 284,439 people who have ever been ranked in the event, and 323rd in Peru. Until May 2007, no official 3×3 solve in the world had been that fast. Across 10 competitions since October 2018, he has put 193 official solves on the record across two events. Solve to solve, his 3×3 times vary about 16% around a typical one; 90% of the 35,811 competitors with ten or more counted rounds hold a tighter spread. His 3×3 best has come down from 13.71 in October 2018 to 10.00, a 27% improvement. Jefferson has entered ten competitions, more competitions than 92% 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.
