Yibo Xu (许一博) has been competing for 9 years. His best event is the 4×4: a personal-best single of 22.14, set at Xuzhou Autumn 2024, puts him in the top 0.2% of the 83,917 people who have ever been ranked in the event, and 22nd in China. Until August 2014, no official 4×4 solve in the world had been that fast. Across 29 competitions since August 2017, he has put 759 official solves on the record across seven events. Solve to solve, his 3×3 times vary about 12% around a typical one, steadier than 73% of the 35,811 competitors with ten or more counted rounds. His 3×3 best has come down from 8.79 in August 2017 to 6.43, a 27% improvement. Yibo has entered 29 competitions, more competitions than 98% of everyone who has ever competed.

Best single per competition, 3×3. Faster is higher — the axis is the right way up.

The story so far

Competitions

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.
