[arin-ppml] Draft Policy ARIN-2014-21: Modification to CI Pool Size per Section 4.4

I'm the first one to seize upon an opportunity to peel band-aids off of
cuts, but I am not sure I see any band-aids below. more like killing
ourselves with a thousand paper cuts.

What would be the usefulness of going from a simple "increase the pool
size" to the below be?

Regarding the sparse allocation bits in your proposal, I thought I read
that staff looked into this and said it wasn't feasible? If that's the
case, why would we go down that path again?  Section 4.4 appears to be
entirely redundant to three of the four sections already. Your suggestions
don't appear to add any clarity to the proposed change at all.

On a side note, I'll point out that this type of activity has been a
frustration for many proposing needed changes to number policy. When we all
put something in that is highly focused on a specific issue, no matter how
simple or articulate that change is --- it enteres a meat grinder and comes
out unrecognizable at the other end. Food for thought.
