Anyway, I think what happens is, for example, the game may assign a .44 PR rating to a particular upgrade. If your current PR before that upgrade is added is a whole number (or, perhaps a whole number plus a tenth, depending on how it deals with rounding of .5), the game will show that the impact of the increase will be .4. However, if you have anything higher hat has not already been rounded up in the PR, the game will show at that point that the marginal impact of the upgrade is .5.
