Yu-Jhih Yeh (葉昱志) has been competing for 12 years. His best event is the Pyraminx: a personal-best single of 3.25, set at Maru Cube Day 2016, puts him in the top 4.5% of the 130,891 people who have ever been ranked in the event, and 67th in Chinese Taipei. Until February 2008, no official Pyraminx solve in the world had been that fast. Across 6 competitions since April 2015, he has put 119 official solves on the record across eight events.

His 3×3 best has come down from 17.83 in April 2015 to 10.59, a 41% improvement. He 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.
