Alder Yu has been competing for a year. His best event is the Pyraminx: a personal-best single of 18.17, set at CubingUSA Great Lakes Championship 2025, puts him in the top 90.1% of the 130,891 people who have ever been ranked in the event, and 26,912th in the United States. Across 6 competitions since June 2025, he has put 68 official solves on the record across four events. Solve to solve, his 3×3 times vary about 25% around a typical one, an early reading from 6 counted rounds. That figure sets aside his 2 DNFs.

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.
