Tiancheng Qi (戚天成) has been competing for 12 years. His best event is the 3×3: a personal-best single of 8.75, set at Longyan Summer Open 2017, puts him in the top 4.3% of the 288,433 people who have ever been ranked in the event, and 1,670th in China. Until May 2008, no official 3×3 solve in the world had been that fast. Across 7 competitions since April 2015, he has put 150 official solves on the record across four events. Solve to solve, his 3×3 times vary about 16% around a typical one; 94% of the 36,406 competitors with ten or more counted rounds hold a tighter spread. His 3×3 best has come down from 15.39 in April 2015 to 8.75, a 43% improvement. Tiancheng has entered seven competitions, more competitions than 88% 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.
