Amendment 2 is actually reintroducing something that was used back in the fifties, when the time came to reconsider redistribution. It's a rule that was used back then that says that any time you do make the change, you don't make a change that would exceed 15%, of what it was before.
We think this is a reasonable way of addressing the fact that population changes can sometimes be rather swift in a 10-year period. This was in fact on the books back in the fifties.
