Chengjie Bao (包成杰) has been competing for 2 years. His best event is the Clock: a personal-best single of 3.51, set at Linhai Newcomers 2025, puts him in the top 1.5% of the 32,048 people who have ever been ranked in the event, and 18th in China. Until July 2018, no official Clock solve in the world had been that fast. Across 11 competitions since June 2024, he has put 107 official solves on the record across three events. His Clock best has come down from 5.30 in June 2024 to 3.51, a 34% improvement. Chengjie has entered eleven competitions, more competitions than 93% of everyone who has ever competed.

The story so far

Competitions

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.
