3×3 · top 30.8% of 284,439 all-time · competing since May 2017 · 2017DONG10
Tianrui Dong (董添瑞) has been competing for 9 years. His best event is the 3×3: a personal-best single of 16.95, set at Heilongjiang Colleges Open 2017, puts him in the top 30.8% of the 284,439 people who have ever been ranked in the event, and 11,237th in China. Across 4 competitions since May 2017, he has put 67 official solves on the record across three events. Solve to solve, his 3×3 times vary about 9% around a typical one, an early reading from 6 counted rounds. That figure sets aside his 2 DNFs. His 3×3 best has come down from 23.89 in May 2017 to 16.95, a 29% improvement. Tianrui 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.
