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 final is a competition's last round; its order decides the podium · a DNF (did not finish) is an attempt with no valid result: a popped piece, an unsolved face, an over-limit memorisation · every solve starts from a computer-generated scramble, the same for every competitor in a round.
