Hello, I sent a longer summary of where this policy discussion is last week, I've pasted a link below to that message in the archive.
http://lists.arin.net/pipermail/arin-ppml/2014-June/028654.html In general, I would say that this draft policy is stalled at this point. The 80% utilization policy underpins a large majority of the current policies and thus is a substantial change. There have been a few people who have voiced their support, but not enough that I believe would allow this policy to move forward as a recommended draft at this point. I would also point out that they current policy also constrains larger providers but in a different way as ARIN is now more closely enforcing the current policy of "efficiently utilized all previous allocations" (4.2.4.1) as noted during the NANOG PPC. Leif, I don't think there is an easy scaling algorithm to apply to utilization. The problem with a scaling algorithm is it likely will be perceived as "unfair" by organizations on one side of the size continuum. (We tried HD ratio for v6 and that was not easily understood, and lead to lots of confusion.)
