In my mind this does not have anything to do with free pool or
transfers, rather it is a measure to save time both for the applicant
and ARIN and to fix a disparity between how small organizations
request space versus large. Right now it is easier for organizations
with large allocations to request space. It is very difficult to make
sure every single small allocation is justified to 80% vs. doing the
same if you only had one or two very large allocations. What happens
in practice is that a smaller organization with many small allocations
(eg. /21 and /22) will have to individually justify every assignment
which may put their utilization at 90%+ before they're allowed to
request space where a larger organization will never run into this
This is something I brought up in 2011 (iirc).
