Ziyi Cong (丛子弋)

3×3 blindfolded · top 9.0% of 12,178 all-time · competing since August 2016 · 2016CONG02

Ziyi Cong (丛子弋) has been competing for 10 years. His best event is the 3×3 blindfolded: a personal-best single of 47.32, set at Guangdong Open 2018, puts him in the top 9.0% of the 12,178 people who have ever been ranked in the event, and 139th in China. Until May 2009, no official 3×3 blindfolded solve in the world had been that fast. Across 22 competitions since August 2016, he has put 312 official solves on the record across eight events. Solve to solve, his 3×3 times vary about 14% around a typical one; 72% of the 35,811 competitors with ten or more counted rounds hold a tighter spread. His 3×3 best has come down from 17.66 in August 2016 to 12.36, a 30% improvement. Ziyi has entered 22 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.
