Joshua Kim

3×3 · top 9.8% of 288,433 all-time · competing since February 2015 · 2015KIMJ01

Joshua Kim has been competing for 12 years. His best event is the 3×3: a personal-best single of 10.77, set at Irvine Winter 2018, puts him in the top 9.8% of the 288,433 people who have ever been ranked in the event, and 571st in Republic of Korea. Until August 2006, no official 3×3 solve in the world had been that fast. Across 8 competitions since February 2015, he has put 109 official solves on the record across four events. Solve to solve, his 3×3 times vary about 12% around a typical one, steadier than 73% of the 36,406 competitors with ten or more counted rounds. His 3×3 best has come down from 27.17 in February 2015 to 10.77, a 60% improvement. Joshua has entered eight competitions, more competitions than 90% of everyone who has ever competed.

The story so far

Competitions

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.
