Jonathan Kang (江进韬)
3×3 · top 4.1% of 284,439 all-time · competing since June 2018 · 2018KANG05
Jonathan Kang (江进韬) has been competing for 8 years. His best event is the 3×3: a personal-best single of 8.68, set at Singapore Skewby March 2026, puts him in the top 4.1% of the 284,439 people who have ever been ranked in the event, and 115th in Singapore. Until July 2008, no official 3×3 solve in the world had been that fast. Across 4 competitions since June 2018, he has put 40 official solves on the record across four events. Solve to solve, his 3×3 times vary about 22% 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 9.69 in June 2018 to 8.68, a 10% improvement. Jonathan 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.
