Jeon Junhyeok (전준혁) has been competing for 9 years. His best event is the 3×3: a personal-best single of 8.23, set at Korea Winter 2019, puts him in the top 3.2% of the 284,439 people who have ever been ranked in the event, and 200th in Republic of Korea. Until July 2008, no official 3×3 solve in the world had been that fast. Across 7 competitions since July 2017, he has put 177 official solves on the record across twelve events. Solve to solve, his 3×3 times vary about 12% around a typical one, steadier than 67% of the 35,811 competitors with ten or more counted rounds. His 3×3 best has come down from 10.40 in July 2017 to 8.23, a 21% improvement. Jeon 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.
