David Yoon

Pyraminx · top 5.7% of 129,321 all-time · competing since July 2022 · 2022YOON03

David Yoon has been competing for 4 years. His best event is the Pyraminx: a personal-best single of 3.56, set at Fort Lee Winter 2026, puts him in the top 5.7% of the 129,321 people who have ever been ranked in the event, and 1,476th in the United States. Until February 2008, no official Pyraminx solve in the world had been that fast. Across 21 competitions since July 2022, he has put 539 official solves on the record across twelve events. Solve to solve, his 3×3 times vary about 13% around a typical one, steadier than 56% of the 35,811 competitors with ten or more counted rounds. His 3×3 best has come down from 46.68 in July 2022 to 10.45, a 78% improvement. David has entered 21 competitions, more competitions than 97% 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.
