Chu Tiến Đạt has been competing for 8 years. His best event is the 2×2: a personal-best single of 1.32, set at Hanoi Summer 2025, puts him in the top 1.4% of the 186,767 people who have ever been ranked in the event, and 23rd in Vietnam. Until November 2008, no official 2×2 solve in the world had been that fast. Across 18 competitions since January 2019, he has put 413 official solves on the record across nine events. Solve to solve, his 3×3 times vary about 10% around a typical one, steadier than 97% of the 35,811 competitors with ten or more counted rounds. His 3×3 best has come down from 11.70 in January 2019 to 8.14, a 30% improvement. Chu has entered 18 competitions, more competitions than 96% 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.
