Yu-Chien Chung (鍾予謙) has been competing for 15 years. His best event is the 2×2: a personal-best single of 1.45, set at Taiwan Championship 2017, puts him in the top 1.9% of the 186,767 people who have ever been ranked in the event, and 46th in Chinese Taipei. Until November 2008, no official 2×2 solve in the world had been that fast. Across 15 competitions since April 2011, he has put 278 official solves on the record across seven events. Solve to solve, his 3×3 times vary about 13% around a typical one; 56% of the 35,811 competitors with ten or more counted rounds hold a tighter spread. His 3×3 best has come down from 18.91 in April 2011 to 10.91, a 42% improvement. He has entered 15 competitions, more competitions than 95% of everyone who has ever competed.

Best single per competition, 3×3. Faster is higher — the axis is the right way up.

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.
