Yifei Tang (唐逸飞) has been competing for 9 years. His best event is the Pyraminx: a personal-best single of 3.81, set at Wuxi Winter 2019, puts him in the top 6.8% of the 129,321 people who have ever been ranked in the event, and 808th in China. Until February 2008, no official Pyraminx solve in the world had been that fast. Across 4 competitions since July 2017, he has put 127 official solves on the record across six events.

Yifei 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.
