2×2 · top 9.5% of 186,767 all-time · competing since July 2016 · 2016JACO04
Mackenzie Jacobs has been competing for 10 years. Her best event is the 2×2: a personal-best single of 2.56, set at Rubik's WCA North American Championship 2024, puts her in the top 9.5% of the 186,767 people who have ever been ranked in the event, and 3,749th in the United States. Until February 2008, no official 2×2 solve in the world had been that fast. Across 17 competitions since July 2016, she has put 328 official solves on the record across four events. Solve to solve, her 3×3 times vary about 13% around a typical one, steadier than 59% of the 35,811 competitors with ten or more counted rounds. Her 3×3 best has come down from 35.56 in July 2016 to 13.55, a 62% improvement. Mackenzie has entered 17 competitions, more competitions than 96% 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.
