Zirui Peng (彭子睿) has been competing for 8 years. His best event is the 3×3: a personal-best single of 10.55, set at Chengdu Summer 2024, puts him in the top 9.2% of the 288,433 people who have ever been ranked in the event, and 3,646th in China. Until August 2006, no official 3×3 solve in the world had been that fast. Across 8 competitions since November 2018, he has put 102 official solves on the record across four events. Solve to solve, his 3×3 times vary about 13% around a typical one, an early reading from 8 counted rounds. His 2×2 best has come down from 4.04 in November 2018 to 2.82, a 30% improvement. Zirui has entered eight competitions, more competitions than 90% 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.
