Alexander Seungu Hu
3×3 · top 4.9% of 284,439 all-time · competing since November 2022 · 2022HUAL02
Alexander Seungu Hu has been competing for 4 years. His best event is the 3×3: a personal-best single of 9.01, set at Guelph 2023, puts him in the top 4.9% of the 284,439 people who have ever been ranked in the event, and 291st in Republic of Korea. Until May 2008, no official 3×3 solve in the world had been that fast. Across 11 competitions since November 2022, he has put 194 official solves on the record across five events. Solve to solve, his 3×3 times vary about 16% around a typical one; 94% of the 35,811 competitors with ten or more counted rounds hold a tighter spread. That figure sets aside his 6 DNFs. His 3×3 best has come down from 18.33 in November 2022 to 9.01, a 51% improvement. Alexander has entered eleven competitions, more competitions than 93% 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.
