Yaromyr Diachenko (Яромир Дьяченко) has been competing for 2 years. His best event is the Pyraminx: a personal-best single of 3.60, set at Ukrainian Nationals 2025, puts him in the top 5.9% of the 130,891 people who have ever been ranked in the event, and 114th in Ukraine. Until February 2008, no official Pyraminx solve in the world had been that fast. Across 7 competitions since May 2024, he has put 284 official solves on the record across ten events. Solve to solve, his 3×3 times vary about 15% around a typical one, an early reading from 9 counted rounds. That figure sets aside his 3 DNFs. His Pyraminx best has come down from 9.75 in May 2024 to 3.60, a 63% improvement. Yaromyr has entered seven competitions, more competitions than 88% 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.
