Derek Han
2×2 · top 4.9% of 186,767 all-time · competing since November 2011 · 2011HAND05
Derek Han has been competing for 15 years. His best event is the 2×2: a personal-best single of 2.03, set at Caltech Fall Open 2014, puts him in the top 4.9% of the 186,767 people who have ever been ranked in the event, and 134th in Republic of Korea. Until February 2008, no official 2×2 solve in the world had been that fast. Across 9 competitions since November 2011, he has put 74 official solves on the record across three events. Solve to solve, his 3×3 times vary about 12% around a typical one, an early reading from 8 counted rounds. That figure sets aside his 3 DNFs. His 3×3 best has come down from 43.91 in November 2011 to 20.08, a 54% improvement. Derek has entered nine competitions, more competitions than 91% 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.
