Yucheng Zhang (张宇程) has been competing for 8 years. His best event is the Pyraminx: a personal-best single of 3.42, set at Shenzhen Cubing 10th Anniversary 2019, puts him in the top 5.2% of the 130,891 people who have ever been ranked in the event, and 629th in China. Until February 2008, no official Pyraminx solve in the world had been that fast. Across 4 competitions since March 2019, he has put 111 official solves on the record across six events.

Yucheng 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.
