Yuntian Jiang (蒋云天) has been competing for 10 years. His best event is the Pyraminx: a personal-best single of 2.44, set at Kunshan Side Events 2021, puts him in the top 2.1% of the 129,321 people who have ever been ranked in the event, and 245th in China.

His 3×3 best has come down from 27.50 in August 2016 to 11.10, a 60% improvement. Yuntian has entered 22 competitions, more competitions than 97% 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.
