This is simply accomodated by mutliplying the maximum utilisation figure by
0.75 for every layer of hierarchy or aggregation in the network. So for
a 3 layer network plus another layer for international aggregation the
maximum utilisation falls to 0.75^4=0.316 == 32%.
This is the theoritical maximum address utilisation that can be achieved
without breaking aggregates.
I think we should penalize anyone who gets a better address utilisation than
this because they are obviously announcing more routes than they need to ;-)
