Yanchen Weng (翁彦辰) has been competing for 10 years. His best event is the Pyraminx: a personal-best single of 2.78, set at Nanjing Autumn 2019, puts him in the top 2.9% of the 129,321 people who have ever been ranked in the event, and 345th in China. Until October 2010, no official Pyraminx solve in the world had been that fast. Across 18 competitions since August 2016, he has put 382 official solves on the record across nine events.

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.
