Maybe I wasn't sufficiently clear. My question was intended to refer to the current allocation policy. 

If I understand your response, you are suggesting that the the issue is not that the policy causes problems for people who want to plan ahead but that ISPs are not sufficiently knowledgable and experienced to do so. I am not sure how changing the way we do a calculation is going to solve this problem.
