I would suggest that we do not abandon the original 80%
rule completely.  Perhaps the policy can start off with:

  If an organization requesting an IPv4 allocation cannot
  meet the utilization rate stated in the primary criteria
  that ARIN uses, than the HD ratio may be applied to
  determine adequate utilization for approval of the
  request.

I don't want to explicitly state the 80% figure and how
it's applied to the most recent allocation or all previous
allocations.  This way, the policy is a little more
flexible to allow a change of the 80% figure elsewhere.

(I've got another thought on this issue that I'm sure I'll
remember just after sending this message. :)
