Se-jun Park

3×3 · top 8.4% of 284,439 all-time · competing since April 2016 · 2016PARK08

Se-jun Park has been competing for 10 years. His best event is the 3×3: a personal-best single of 10.33, set at Korean Championship 2016, puts him in the top 8.4% of the 284,439 people who have ever been ranked in the event, and 482nd in Republic of Korea. Until May 2007, no official 3×3 solve in the world had been that fast. Across 3 competitions since April 2016, he has put 45 official solves on the record across five events. Solve to solve, his 3×3 times vary about 15% around a typical one, an early reading from 5 counted rounds. His 3×3 best has come down from 11.76 in April 2016 to 10.33, a 12% improvement. He has entered three competitions, more competitions than 69% 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.
