2×2 · top 2.2% of 186,767 all-time · competing since March 2022 · 2022KALL01
Sofia Källström has been competing for 4 years. Her best event is the 2×2: a personal-best single of 1.52, set at Popular 'n Blind Flen 2022, puts her in the top 2.2% of the 186,767 people who have ever been ranked in the event, and 90th in Sweden. Until November 2008, no official 2×2 solve in the world had been that fast. Across 10 competitions since March 2022, she has put 281 official solves on the record across three events. Solve to solve, her 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. Her 3×3 best has come down from 10.46 in March 2022 to 8.68, a 17% improvement. Sofia 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.
