Seunghyo Ryu has been competing for 5 years. His best event is the 3×3: a personal-best single of 8.80, set at Korean Championship 2022, puts him in the top 4.4% of the 284,439 people who have ever been ranked in the event, and 263rd in Republic of Korea. Until May 2008, no official 3×3 solve in the world had been that fast. Across 24 competitions since December 2021, he has put 419 official solves on the record across six events.

His 3×3 best has come down from 15.47 in December 2021 to 8.80, a 43% improvement. Seunghyo has entered 24 competitions, more competitions than 97% of everyone who has ever competed.

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.
