Choe Seong-bin has been competing for 11 years. His best event is the 3×3: a personal-best single of 11.09, set at Korean Championship 2017, puts him in the top 10.8% of the 284,439 people who have ever been ranked in the event, and 610th in Republic of Korea. Across 5 competitions since October 2015, he has put 43 official solves on the record across three events. Solve to solve, his 3×3 times vary about 11% around a typical one, an early reading from 6 counted rounds. That figure sets aside his 2 DNFs. His 3×3 best has come down from 19.51 in October 2015 to 11.09, a 43% improvement. Choe has entered five competitions, more competitions than 83% 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.
