2×2 · top 3.8% of 186,767 all-time · competing since January 2019 · 2019KAUF01
Aaron Kaufer has been competing for 8 years. His best event is the 2×2: a personal-best single of 1.84, set at Bay Area Speedcubin' 63 - Atherton 2024, puts him in the top 3.8% of the 186,767 people who have ever been ranked in the event, and 1,501st in the United States. Until February 2008, no official 2×2 solve in the world had been that fast. Across 14 competitions since January 2019, he has put 160 official solves on the record across three events. Solve to solve, his 3×3 times vary about 13% around a typical one, steadier than 50% of the 35,811 competitors with ten or more counted rounds. His 3×3 best has come down from 15.26 in January 2019 to 10.34, a 32% improvement. Aaron has entered 14 competitions, more competitions than 95% 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.
