Kyoungmin Choi (최경민) has been competing for 20 years. His best event is the 2×2: a personal-best single of 2.59, set at Suwon Cube Championship 2008, puts him in the top 9.8% of the 186,767 people who have ever been ranked in the event, and 286th in Republic of Korea. Until February 2008, no official 2×2 solve in the world had been that fast. Across 7 competitions since January 2007, he has put 157 official solves on the record across five events. Solve to solve, his 3×3 times vary about 11% around a typical one, steadier than 84% of the 35,811 competitors with ten or more counted rounds. His 2×2 best has come down from 4.83 in January 2007 to 2.59, a 46% improvement. Kyoungmin has entered seven competitions, more competitions than 88% 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.
