Shian Sung (성시안)
Clock · top 7.1% of 32,048 all-time · competing since January 2025 · 2025SUNG03
Shian Sung (성시안) has been competing for a year. His best event is the Clock: a personal-best single of 5.96, set at Korea Open 2026, puts him in the top 7.1% of the 32,048 people who have ever been ranked in the event, and 46th in Republic of Korea. Until July 2011, no official Clock solve in the world had been that fast. Across 8 competitions since January 2025, he has put 195 official solves on the record across seven events. Solve to solve, his 3×3 times vary about 11% around a typical one, an early reading from 8 counted rounds. That figure sets aside his 3 DNFs. His Clock best has come down from 12.03 in June 2025 to 5.96, a 50% improvement. Shian has entered eight competitions, more competitions than 90% 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.
