Thanks for the redline document.  I find it quite useful, especially with the inline comments.

I am confused with this plus a similar 4.4.1 statement of placing an additional /16 in reserve.  In total, will all of 4.4 be a single /16 equivalent?  Or is the proposal to add another /16 beyond what is already reserved in the existing 4.4 text.

I could also read this as a /16 is effectively reserved for 4.4.3, as 4.4.2 is exempt from utilizing the reservation and 4.4.1 has its own /16 equivalent.

I am indifferent to making this change.  If we make a policy change, I would support leaving this in.  However, I am not sure that a change is fully necessary.

In regards to Andrew's question in the PDF - "Does the policy need text on how ARIN should determine block size for exchange points?" - I'll come back with another question.  How do staff today make determination on block size under this policy?  I would expect that whatever determination criteria is used today would still be valid with a smaller block size.

I do see that this policy breaks separate methods of issuance out, but I don't know that it makes the Micro-allocation policy any clearer.  I am not sure that a policy change is necessary.
