Jun Xu (徐俊)

3×3 blindfolded · top 5.1% of 12,178 all-time · competing since August 2011 · 2011XUJU01

Jun Xu (徐俊) has been competing for 15 years. His best event is the 3×3 blindfolded: a personal-best single of 33.80, set at Nanjing Autumn 2016, puts him in the top 5.1% of the 12,178 people who have ever been ranked in the event, and 91st in China. Until February 2010, no official 3×3 blindfolded solve in the world had been that fast. Across 18 competitions since August 2011, he has put 203 official solves on the record across seven events. Solve to solve, his 3×3 times vary about 13% around a typical one; 58% of the 35,811 competitors with ten or more counted rounds hold a tighter spread. His 3×3 best has come down from 12.15 in August 2011 to 9.23, a 24% improvement. Jun has entered 18 competitions, more competitions than 96% 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.
