Haolong Du (杜昊龍) has been competing for 9 years. His best event is the 3×3: a personal-best single of 9.57, set at Brisbane Summer 2023, puts him in the top 6.3% of the 288,433 people who have ever been ranked in the event, and 2,495th in China. Until November 2007, no official 3×3 solve in the world had been that fast. Across 8 competitions since September 2017, he has put 125 official solves on the record across two events. Solve to solve, his 3×3 times vary about 11% around a typical one, steadier than 91% of the 36,406 competitors with ten or more counted rounds. His 3×3 best has come down from 13.38 in September 2017 to 9.57, a 28% improvement. Haolong 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.
