Pyraminx · top 5.9% of 130,891 all-time · competing since August 2019 · 2019OUJI01
Jiajie Ou (区嘉杰) has been competing for 7 years. His best event is the Pyraminx: a personal-best single of 3.60, set at Shenzhen Cubing 10th Anniversary 2019, puts him in the top 5.9% of the 130,891 people who have ever been ranked in the event, and 715th in China. Until February 2008, no official Pyraminx solve in the world had been that fast. Across 4 competitions since August 2019, he has put 133 official solves on the record across eleven events. Solve to solve, his 3×3 times vary about 7% around a typical one, an early reading from 5 counted rounds. That figure sets aside his 2 DNFs. His 3×3 best has come down from 12.76 in August 2019 to 9.73, a 24% improvement. Jiajie has entered four competitions, more competitions than 78% 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.
