Jiaqi Dai (戴家麒) has been competing for 15 years. His best event is the 2×2: a personal-best single of 4.86, set at Shanghai Snowball Winter 2011, puts him in the top 37.5% of the 186,767 people who have ever been ranked in the event, and 6,472nd in China. Across 6 competitions since April 2011, he has put 89 official solves on the record across six events. Solve to solve, his 3×3 times vary about 12% around a typical one, an early reading from 5 counted rounds. That figure sets aside his 2 DNFs.

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.
