Son Seul-Gi

3×3 · top 8.1% of 284,439 all-time · competing since January 2006 · 2006SEUL01

Son Seul-Gi has been competing for 21 years. Her best event is the 3×3: a personal-best single of 10.21, set at Korea Cube Championship 2009, puts her in the top 8.1% of the 284,439 people who have ever been ranked in the event, and 462nd in Republic of Korea. Until May 2007, no official 3×3 solve in the world had been that fast. Across 8 competitions since January 2006, she has put 250 official solves on the record across eight events. Solve to solve, her 3×3 times vary about 12% around a typical one, steadier than 72% of the 35,811 competitors with ten or more counted rounds. Her 3×3 best has come down from 18.73 in January 2006 to 10.21, a 45% improvement. Son has entered eight competitions, more competitions than 90% of everyone who has ever competed.

Best single per competition, 3×3. Faster is higher — the axis is the right way up.

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.
