Ludwig Choi

Pyraminx · top 6.9% of 129,321 all-time · competing since January 2011 · 2011CHOI02

Ludwig Choi has been competing for 16 years. His best event is the Pyraminx: a personal-best single of 3.83, set at Hessen Open 2014, puts him in the top 6.9% of the 129,321 people who have ever been ranked in the event, and 157th in Germany. Until February 2008, no official Pyraminx solve in the world had been that fast. Across 21 competitions since January 2011, he has put 919 official solves on the record across twelve events. Solve to solve, his 3×3 times vary about 12% around a typical one, steadier than 72% of the 35,811 competitors with ten or more counted rounds. His 3×3 best has come down from 16.84 in January 2011 to 10.02, a 40% improvement. Ludwig has entered 21 competitions, more competitions than 97% 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.
