Kai Song (宋凯)

3×3 one-handed · top 6.2% of 73,695 all-time · competing since September 2018 · 2018SONG34

Kai Song (宋凯) has been competing for 8 years. His best event is the 3×3 one-handed: a personal-best single of 14.05, set at Taizhou Open 2019, puts him in the top 6.2% of the 73,695 people who have ever been ranked in the event, and 586th in China. Until September 2009, no official 3×3 one-handed solve in the world had been that fast. Across 4 competitions since September 2018, he has put 68 official solves on the record across three events. Solve to solve, his 3×3 times vary about 13% around a typical one, an early reading from 7 counted rounds. That figure sets aside his 2 DNFs. Kai 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.
