Seung-Woo Choi

3×3 · top 9.7% of 284,439 all-time · competing since May 2009 · 2009CHOI01

Seung-Woo Choi has been competing for 17 years. His best event is the 3×3: a personal-best single of 10.75, set at Eagle Peak - San Diego Open 2012, puts him in the top 9.7% of the 284,439 people who have ever been ranked in the event, and 554th in Republic of Korea. Until August 2006, no official 3×3 solve in the world had been that fast. Across 8 competitions since May 2009, he has put 132 official solves on the record across four events. Solve to solve, his 3×3 times vary about 11% around a typical one, steadier than 86% of the 35,811 competitors with ten or more counted rounds. That figure sets aside his 5 DNFs. His 3×3 best has come down from 30.03 in May 2009 to 10.75, a 64% improvement. He has entered eight competitions, more competitions than 90% 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.
