Square-1 · top 5.6% of 25,662 all-time · competing since July 2013 · 2013JIAN08
Zhinan Jiang (江志楠) has been competing for 13 years. His best event is the Square-1: a personal-best single of 9.68, set at Beijing Ten Years Open 2017, puts him in the top 5.6% of the 25,662 people who have ever been ranked in the event, and 73rd in China. Until October 2010, no official Square-1 solve in the world had been that fast. Across 6 competitions since July 2013, he has put 140 official solves on the record across seven events. Solve to solve, his 3×3 times vary about 11% around a typical one, steadier than 87% of the 36,406 competitors with ten or more counted rounds. His 3×3 best has come down from 14.33 in July 2013 to 10.42, a 27% improvement. Zhinan 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.
