Jiajun Wu (吴佳骏)

3×3 one-handed · top 0.98% of 73,695 all-time · competing since July 2017 · 2017WUJI08

Jiajun Wu (吴佳骏) has been competing for 9 years. His best event is the 3×3 one-handed: a personal-best single of 9.89, set at Taizhou Open 2019, puts him in the top 0.98% of the 73,695 people who have ever been ranked in the event, and 82nd in China. Until December 2011, no official 3×3 one-handed solve in the world had been that fast. Across 8 competitions since July 2017, he has put 254 official solves on the record across seven events. Solve to solve, his 3×3 times vary about 13% around a typical one; 59% of the 35,811 competitors with ten or more counted rounds hold a tighter spread. His 3×3 best has come down from 13.12 in July 2017 to 7.36, a 44% improvement. Jiajun has entered eight competitions, more competitions than 90% of everyone who has ever competed.

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.
