Mingmin Dai (戴铭民) has been competing for 10 years. His best event is the 3×3: a personal-best single of 11.18, set at Saint-Maurice Sunday Open 2018, puts him in the top 11.1% of the 284,439 people who have ever been ranked in the event, and 4,326th in China. Across 12 competitions since March 2016, he has put 142 official solves on the record across five events. Solve to solve, his 3×3 times vary about 12% around a typical one, steadier than 65% of the 35,811 competitors with ten or more counted rounds. That figure sets aside his 6 DNFs. His 3×3 best has come down from 18.21 in March 2016 to 11.18, a 39% improvement. Mingmin has entered twelve competitions, more competitions than 94% 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.
