Shoubo Zhang (张守博)
2×2 · top 8.0% of 189,179 all-time · competing since September 2024 · 2024ZHAS04
Shoubo Zhang (张守博) has been competing for 2 years. His best event is the 2×2: a personal-best single of 2.40, set at Xuzhou Autumn 2024, puts him in the top 8.0% of the 189,179 people who have ever been ranked in the event, and 1,173rd in China. Until February 2008, no official 2×2 solve in the world had been that fast. Across 5 competitions since September 2024, he has put 63 official solves on the record across three events. Solve to solve, his 3×3 times vary about 10% around a typical one, an early reading from 6 counted rounds. That figure sets aside his 2 DNFs. His 3×3 best has come down from 13.47 in September 2024 to 11.34, a 16% improvement. Shoubo 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.
