Ryan Minjun Cho

Pyraminx · top 0.39% of 129,321 all-time · competing since July 2014 · 2014CHOR01

Ryan Minjun Cho has been competing for 12 years. His best event is the Pyraminx: a personal-best single of 1.48, set at Michigan 2023, puts him in the top 0.39% of the 129,321 people who have ever been ranked in the event, and 13th in Canada. Until March 2013, no official Pyraminx solve in the world had been that fast. Across 43 competitions since July 2014, he has put 1,805 official solves on the record across 15 events. Solve to solve, his 3×3 times vary about 12% around a typical one, steadier than 62% of the 35,811 competitors with ten or more counted rounds. That figure sets aside his 25 DNFs. His 3×3 best has come down from 32.07 in July 2014 to 7.64, a 76% improvement. Ryan has entered 43 competitions, more competitions than 99% 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.
