Haobo Zhang (张浩博) has been competing for 11 years. His best event is the Pyraminx: a personal-best single of 3.38, set at China Championship 2017, puts him in the top 5.0% of the 129,321 people who have ever been ranked in the event, and 597th in China. Until February 2008, no official Pyraminx solve in the world had been that fast. Across 7 competitions since August 2015, he has put 317 official solves on the record across eleven 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.
