Xin Shi (石欣) has been competing for 16 years. His best event is the 3×3 blindfolded: a personal-best single of 22.56, set at Guangdong Open 2021, puts him in the top 2.2% of the 12,178 people who have ever been ranked in the event, and 31st in China. Until November 2014, no official 3×3 blindfolded solve in the world had been that fast. Across 96 competitions since July 2010, he has put 2,035 official solves on the record across 17 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 24.84 in July 2010 to 8.27, a 67% improvement. Xin has entered 96 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.
