Yidi Guo (郭一荻)

Pyraminx · top 5.8% of 129,321 all-time · competing since August 2018 · 2018GUOY05

Yidi Guo (郭一荻) has been competing for 8 years. His best event is the Pyraminx: a personal-best single of 3.59, set at Shenyang Spring 2024, puts him in the top 5.8% of the 129,321 people who have ever been ranked in the event, and 692nd in China. Until February 2008, no official Pyraminx solve in the world had been that fast. Across 8 competitions since August 2018, he has put 178 official solves on the record across six events. Solve to solve, his 3×3 times vary about 14% around a typical one; 77% of the 35,811 competitors with ten or more counted rounds hold a tighter spread. His 3×3 best has come down from 23.06 in August 2018 to 11.34, a 51% improvement. Yidi has entered eight competitions, more competitions than 90% of everyone who has ever competed.

The story so far

Competitions

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.
