Sieon Jeong

2×2 · top 4.1% of 186,767 all-time · competing since March 2024 · 2024JEON04

Sieon Jeong has been competing for 2 years. His best event is the 2×2: a personal-best single of 1.90, set at Beat the Clock Westminster 2024, puts him in the top 4.1% of the 186,767 people who have ever been ranked in the event, and 113th in Republic of Korea. Until February 2008, no official 2×2 solve in the world had been that fast. Across 3 competitions since March 2024, he has put 59 official solves on the record across six events. Solve to solve, his 3×3 times vary about 11% around a typical one, an early reading from 6 counted rounds. That figure sets aside his 2 DNFs. His 3×3 best has come down from 17.14 in March 2024 to 15.37, a 10% improvement. Sieon has entered three competitions, more competitions than 69% 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.
