Yubo Zhao (赵誉博) has been competing for 2 years. His best event is the 3×3: a personal-best single of 7.89, set at Xuzhou Open 2025, puts him in the top 2.6% of the 284,439 people who have ever been ranked in the event, and 943rd in China. Until July 2008, no official 3×3 solve in the world had been that fast. Across 7 competitions since May 2024, he has put 137 official solves on the record across four events. Solve to solve, his 3×3 times vary about 13% around a typical one; 56% of the 35,811 competitors with ten or more counted rounds hold a tighter spread. His 3×3 best has come down from 13.45 in May 2024 to 7.89, a 41% improvement. Yubo 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.
