Nguyen Duc Khoi has been competing for 12 years. His best event is the 2×2: a personal-best single of 2.51, set at HCMC Summer Open 2016, puts him in the top 9.1% of the 189,179 people who have ever been ranked in the event, and 162nd in Vietnam.

Nguyen has entered five competitions, more competitions than 83% 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.
