Pyraminx · top 0.93% of 129,321 all-time · competing since December 2021 · 2021KIMC02

Chaeyoung Kim has been competing for 5 years. His best event is the Pyraminx: a personal-best single of 1.87, set at Geelong Winter 2024, puts him in the top 0.93% of the 129,321 people who have ever been ranked in the event, and 19th in Republic of Korea. Until April 2012, no official Pyraminx solve in the world had been that fast. Across 18 competitions since December 2021, he has put 712 official solves on the record across eight events. Solve to solve, his 3×3 times vary about 14% around a typical one; 78% of the 35,811 competitors with ten or more counted rounds hold a tighter spread. His 3×3 best has come down from 24.77 in December 2021 to 7.68, a 69% improvement. Chaeyoung has entered 18 competitions, more competitions than 96% 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.
