Jialin Jia (贾佳林)

3×3 · top 7.8% of 284,439 all-time · competing since November 2018 · 2018JIAJ02

Jialin Jia (贾佳林) has been competing for 8 years. His best event is the 3×3: a personal-best single of 10.13, set at Potomac Speedcubing 2020, puts him in the top 7.8% of the 284,439 people who have ever been ranked in the event, and 3,069th in China. Until May 2007, no official 3×3 solve in the world had been that fast. Across 4 competitions since November 2018, he has put 40 official solves on the record across three events. Solve to solve, his 3×3 times vary about 12% around a typical one, an early reading from 6 counted rounds. His 3×3 best has come down from 22.95 in November 2018 to 10.13, a 56% improvement. Jialin has entered four competitions, more competitions than 78% 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.
