Skewb · top 3.3% of 73,281 all-time · competing since December 2019 · 2019LEEH02
HyunJin Lee (이현진) has been competing for 7 years. His best event is the Skewb: a personal-best single of 2.61, set at Ansan Spring 2023, puts him in the top 3.3% of the 73,281 people who have ever been ranked in the event, and 32nd in Republic of Korea. Until February 2014, no official Skewb solve in the world had been that fast. Across 15 competitions since December 2019, he has put 329 official solves on the record across seven events. Solve to solve, his 3×3 times vary about 12% around a typical one, steadier than 65% of the 35,811 competitors with ten or more counted rounds. His 3×3 best has come down from 13.04 in December 2019 to 8.98, a 31% improvement. HyunJin has entered 15 competitions, more competitions than 95% 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.
