Mix Chang (张健) has been competing for 14 years. His best event is the 2×2: a personal-best single of 2.27, set at BUAA Open 2013, puts him in the top 6.8% of the 186,767 people who have ever been ranked in the event, and 959th in China. Until February 2008, no official 2×2 solve in the world had been that fast. Across 4 competitions since November 2012, he has put 114 official solves on the record across seven events.

Mix has entered four competitions, more competitions than 78% 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.
