Aihong Yu (于爱红)
Pyraminx · top 4.7% of 129,321 all-time · competing since March 2024 · 2024YUAI01
Aihong Yu (于爱红) has been competing for 2 years. Her best event is the Pyraminx: a personal-best single of 3.30, set at Xi'an Summer 2025, puts her in the top 4.7% of the 129,321 people who have ever been ranked in the event, and 561st in China. Until February 2008, no official Pyraminx solve in the world had been that fast. Across 6 competitions since March 2024, she has put 69 official solves on the record across three events. Solve to solve, her 3×3 times vary about 13% around a typical one, an early reading from 6 counted rounds. Her 3×3 best has come down from 22.73 in March 2024 to 13.13, a 42% improvement. Aihong has entered six competitions, more competitions than 86% 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.
