Haitao Yu (于海涛) has been competing for 9 years. His best event is the Pyraminx: a personal-best single of 4.35, set at Lanzhou Autumn 2018, puts him in the top 9.4% of the 129,321 people who have ever been ranked in the event, and 1,117th in China.

Haitao 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.
