2×2 · top 8.7% of 186,767 all-time · competing since September 2018 · 2018XIAO16
Dunbo Xiao has been competing for 8 years. His best event is the 2×2: a personal-best single of 2.48, set at Hessen Open 2019, puts him in the top 8.7% of the 186,767 people who have ever been ranked in the event, and 1,285th in China. Until February 2008, no official 2×2 solve in the world had been that fast. Across 5 competitions since September 2018, he has put 102 official solves on the record across four events. Solve to solve, his 3×3 times vary about 16% around a typical one, an early reading from 9 counted rounds. His 3×3 best has come down from 17.42 in September 2018 to 14.96, a 14% improvement. Dunbo 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.
