2×2 · top 3.1% of 186,767 all-time · competing since July 2018 · 2018INCH01

Choi Young In (최영인) has been competing for 8 years. His best event is the 2×2: a personal-best single of 1.71, set at Play Cube X4 2019, puts him in the top 3.1% of the 186,767 people who have ever been ranked in the event, and 89th in Republic of Korea. Until February 2008, no official 2×2 solve in the world had been that fast. Across 6 competitions since July 2018, he has put 158 official solves on the record across nine events. Solve to solve, his 3×3 times vary about 12% around a typical one, steadier than 64% of the 35,811 competitors with ten or more counted rounds. His 3×3 best has come down from 13.45 in July 2018 to 8.46, a 37% improvement. Choi has entered six competitions, more competitions than 86% 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.
