2×2 · top 9.2% of 189,179 all-time · competing since November 2014 · 2014ZHEN10
Zi-Zhao Zheng has been competing for 12 years. His best event is the 2×2: a personal-best single of 2.53, set at Langenstein Summer 2026, puts him in the top 9.2% of the 189,179 people who have ever been ranked in the event, and 62nd in Austria. Until February 2008, no official 2×2 solve in the world had been that fast. Across 5 competitions since November 2014, he has put 193 official solves on the record across 14 events. Solve to solve, his 3×3 times vary about 13% around a typical one, an early reading from 9 counted rounds. That figure sets aside his 3 DNFs. His 3×3 best has come down from 20.00 in November 2014 to 13.63, a 32% improvement. He has entered five competitions, more competitions than 83% 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.
