Yoo Seung Woo (유승우) has been competing for 8 years. His best event is the Pyraminx: a personal-best single of 2.97, set at Korean Championship 2019, puts him in the top 3.5% of the 129,321 people who have ever been ranked in the event, and 63rd in Republic of Korea. Until February 2008, no official Pyraminx solve in the world had been that fast. Across 10 competitions since July 2018, he has put 96 official solves on the record across four events. Solve to solve, his 3×3 times vary about 16% around a typical one, an early reading from 5 counted rounds. His Pyraminx best has come down from 10.06 in July 2018 to 2.97, a 70% improvement. Yoo 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.
