Dongjae Jang (장동재) has been competing for 5 years. His best event is the 2×2: a personal-best single of 2.14, set at Rubik's WCA World Championship 2023, puts him in the top 5.7% of the 186,767 people who have ever been ranked in the event, and 161st in Republic of Korea. Until February 2008, no official 2×2 solve in the world had been that fast. Across 8 competitions since December 2021, he has put 127 official solves on the record across six events. Solve to solve, his 3×3 times vary about 17% around a typical one; 95% of the 35,811 competitors with ten or more counted rounds hold a tighter spread. His 3×3 best has come down from 13.69 in December 2021 to 10.04, a 27% improvement. Dongjae has entered eight competitions, more competitions than 90% 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.
