Sure. It is based on the "assumption" that it takes some experience in management to be "good" and managing, and that having too many rings to manage dilutes ones ability to manage all as well as if that were the only one to manage. So, between a few rings and a bunch of Rings is deemed a "good" number to have. So, in that range a member is given a "bonus" to their score. Alternatively I suppose we could take away if you have "too few" as well as "too many", the affect is the same, but this sounded more interesting.
