Zhengtao Yu (俞正涛) has been competing for 9 years. His best event is the 4×4: a personal-best single of 25.82, set at Huzhou Open 2024, puts him in the top 0.95% of the 85,040 people who have ever been ranked in the event, and 93rd in China. Until June 2013, no official 4×4 solve in the world had been that fast. Across 8 competitions since May 2017, he has put 300 official solves on the record across nine events. Solve to solve, his 3×3 times vary about 12% around a typical one, steadier than 67% of the 36,406 competitors with ten or more counted rounds. His 3×3 best has come down from 9.50 in May 2017 to 6.88, a 28% improvement. Zhengtao 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.
