Possibly 5 is the number of rotations a robot must do before/after scoring or to score. Or, and I'm just throwing ideas out here, the number five on the diamond plate disc may mean that there are five areas in which a team/robot can score from and instead of the traditional flooring the "scoring areas" are diamond plated. But this is my first year on a FIRST team so I don't have any great information to base it on.
