3×3 · top 4.2% of 288,433 all-time · competing since November 2020 · 2020PIAO01
Bocheng Piao (朴博成) has been competing for 6 years. His best event is the 3×3: a personal-best single of 8.69, set at Rubik's WCA World Championship 2023, puts him in the top 4.2% of the 288,433 people who have ever been ranked in the event, and 1,619th in China. Until July 2008, no official 3×3 solve in the world had been that fast. Across 7 competitions since November 2020, he has put 102 official solves on the record across five events. Solve to solve, his 3×3 times vary about 10% around a typical one, steadier than 95% of the 36,406 competitors with ten or more counted rounds. His 3×3 best has come down from 15.65 in November 2020 to 8.69, a 44% improvement. Bocheng has entered seven competitions, more competitions than 88% 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.
