We see that the swings are not very great over this period. The absolute variation of swing between regions is not actually greater than previous years (1992-1997). But since they are based around a much smaller average swing, they are more relatively diffuse. The Uniform National Swing assumption is that these points are tightly clustered. This assumption is the basis for the Battlemap calculations.
