Chen-Chia Chang (張宸嘉) has been competing for 2 years. His best event is the 2×2: a personal-best single of 2.50, set at Hsinchu Summer Open 2025, puts him in the top 8.9% of the 186,767 people who have ever been ranked in the event, and 247th in Chinese Taipei. Until February 2008, no official 2×2 solve in the world had been that fast. Across 4 competitions since June 2024, he has put 29 official solves on the record across two events. His 3×3 best has come down from 21.60 in June 2024 to 13.44, a 38% improvement. He 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.
