Yuko Aoyagi (青柳裕子) has been competing for 8 years. Her best event is the Pyraminx: a personal-best single of 4.22, set at Kansai BLD Summer 2026, puts her in the top 8.8% of the 129,321 people who have ever been ranked in the event, and 105th in Japan.

Her 3×3 best has come down from 59.20 in October 2018 to 16.39, a 72% improvement. Yuko has entered 23 competitions, more competitions than 97% 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.
