Pyraminx · top 6.5% of 129,321 all-time · competing since May 2016 · 2016KIMJ10
Ju Hyeon Kim has been competing for 10 years. His best event is the Pyraminx: a personal-best single of 3.75, set at Korean Championship 2017, puts him in the top 6.5% of the 129,321 people who have ever been ranked in the event, and 109th in Republic of Korea. Until February 2008, no official Pyraminx solve in the world had been that fast. Across 10 competitions since May 2016, he has put 194 official solves on the record across ten events. Solve to solve, his 3×3 times vary about 11% around a typical one, steadier than 91% of the 35,811 competitors with ten or more counted rounds. That figure sets aside his 4 DNFs. His 3×3 best has come down from 22.80 in May 2016 to 11.12, a 51% improvement. Ju has entered ten competitions, more competitions than 92% 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.
