Jung YoonHo (정윤호)
Skewb · top 8.9% of 73,281 all-time · competing since March 2025 · 2025YOON02
Jung YoonHo (정윤호) has been competing for a year. His best event is the Skewb: a personal-best single of 3.69, set at Hamoye Jinju 2026, puts him in the top 8.9% of the 73,281 people who have ever been ranked in the event, and 96th in Republic of Korea. Until February 2014, no official Skewb solve in the world had been that fast. Across 6 competitions since March 2025, he has put 160 official solves on the record across twelve events. Solve to solve, his 3×3 times vary about 20% 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 36.13 in March 2025 to 13.80, a 62% improvement. Jung has entered six competitions, more competitions than 86% 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.
