Here's the problem.  When a provider comes back to ask for more
IPv6 space, or is audited, or even puts in their intial request how
is ARIN staff supposed to evaluate "a low number" of subnets.  Is
that 2?  50?  50,000?

The current policy has two problems.

1) It states the sizes are only a guideline.  Thus ARIN staff is pretty
   much forced to accept a /48 for everything, including a dial-up PC.

2) The current policy, even if it were not a guideline, uses the same
   vague langugage.

I thought an HD-Ratio of .25 was generous, however if the community
wants it to be .10, or .01 I'm fine with that too.  I just feel
strongly that ARIN staff be given a measureable critera rather than
a amazingly vague "guideline".
