4×4 · top 4.3% of 85,040 all-time · competing since February 2020 · 2020SIMS01
Kaimin Sims has been competing for 7 years. His best event is the 4×4: a personal-best single of 32.10, set at UMBC Spring 2025, puts him in the top 4.3% of the 85,040 people who have ever been ranked in the event, and 691st in the United States. Until November 2010, no official 4×4 solve in the world had been that fast. Across 3 competitions since February 2020, he has put 60 official solves on the record across four events. Solve to solve, his 3×3 times vary about 15% around a typical one, an early reading from 5 counted rounds. His 3×3 best has come down from 14.76 in February 2020 to 9.28, a 37% improvement. Kaimin 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.
