Benjamin Chu

2×2 · top 6.9% of 186,767 all-time · competing since November 2012 · 2012CHUB01

Benjamin Chu has been competing for 14 years. His best event is the 2×2: a personal-best single of 2.28, set at Berkeley Mind Sports 2014, puts him in the top 6.9% of the 186,767 people who have ever been ranked in the event, and 2,720th in the United States. Until February 2008, no official 2×2 solve in the world had been that fast. Across 14 competitions since November 2012, he has put 314 official solves on the record across five 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 19.97 in November 2012 to 10.52, a 47% improvement. Benjamin has entered 14 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.
