Cheng Zhang (张成)
3×3 blindfolded · top 8.0% of 12,178 all-time · competing since November 2017 · 2017ZHAC06
Cheng Zhang (张成) has been competing for 9 years. His best event is the 3×3 blindfolded: a personal-best single of 44.14, set at Nanchang Winter 2019, puts him in the top 8.0% of the 12,178 people who have ever been ranked in the event, and 128th in China. Until August 2009, no official 3×3 blindfolded solve in the world had been that fast. Across 13 competitions since November 2017, he has put 138 official solves on the record across two events. Solve to solve, his 3×3 times vary about 14% around a typical one; 63% of the 35,811 competitors with ten or more counted rounds hold a tighter spread. His 3×3 best has come down from 13.35 in November 2017 to 10.96, an 18% improvement. Cheng has entered 13 competitions, more competitions than 94% of everyone who has ever competed.

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.
