Kaixin Lin (林凯新)
3×3 · top 6.1% of 284,439 all-time · competing since August 2015 · 2015LINK01
Kaixin Lin (林凯新) has been competing for 11 years. His best event is the 3×3: a personal-best single of 9.49, set at China's 10th Anniversary Championship 2017, puts him in the top 6.1% of the 284,439 people who have ever been ranked in the event, and 2,345th in China. Until February 2008, no official 3×3 solve in the world had been that fast. Across 6 competitions since August 2015, he has put 90 official solves on the record across three events. Solve to solve, his 3×3 times vary about 13% around a typical one, steadier than 60% of the 35,811 competitors with ten or more counted rounds. Kaixin has entered six competitions, more competitions than 86% 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.
