I am suspicious that we have a little bit of apples and oranges going on.
Lets say I am a wireless provider (I am) and I have a /20 which has more
than 80% of the address reassigned/allocated and in "use" and am preparing to 
another allocation. Further let's say that when looking at how the addresses
are being used there are a number of towers that have /27's assigned to each 

As I read it, the original question seemed to assume that each sector's /27 
to be 80% utilized. That seems to me to be very difficult if not impossible. 
the choice is /28 or /27 if a /28 is too small then a /27 is appropriate. The 
I have is are we having to get to this detail, (I assume we are) and even if 
we are
do we really want to tell operators that they have to renumber their affected 
when they go from 14 to 15 customers on a sector or tell him that he needs to 
layer 2 transport instead of subnetting on a sector basis which seems to me to 
a design choice beyond our scope.

As bandwidth requirements have risen the number of customers on a single 
sector has fallen
so this kind of problem is more likely now than in the past.

If that is not what the original poster meant please correct me.
