Why is the base of the formation not required to be centered in a grid square?
The judging criteria for records are designed to be used with both small and very large formations. In larger flocks, there are secondary and tertiary bases in addition to the person in front. People at the back have no view of the primary base, and the flight dynamics reflect this. The grid is placed over the formation using a “best fit” method. If there is a way to fit all of the participants in the grid, that is how it will be oriented.
