Jason,

I've been reviewing the record for ARIN-2016-2 and ARIN-2016-4;

https://www.arin.net/policy/proposals/2016_2.html
https://www.arin.net/policy/proposals/2016_4.html

Please remember that 2016-2 and 2016-4 have overlapping changes, this was
noted in the comments of 2016-4, prop-227 is 2016-2.

See my comments inline;

2016-2 had a slightly delayed implementation, it was impemented on
04/20/217, from the other policys approved at the same time.

While it is unfortunate we didn't explicitly say that the sub-sections were
to be deleted, it however seems clear to me that was the intent.  The
Problem Statement makes it clear 4.2.2.1.1 is no longer valid, further
several of the sub-sections are obviously incoporated in the new text of
4.2.2 including 4.2.2.1.3, which based on the coment within 2016-4 was
removed because 2016-2 was also adopted.

Even if 4.2.2.1.3 wasn't removed ARIN-2016-2 would have clearlly changed it
to 24 months.

I don't know if you also support 2016-2, but it quite cleary changes the 90
day supply (for non-transfers) to a 2 year supply (for both transfers and
non-transfers), in fact this is conditionally noted in the comments for
2016-4.

I believe the overlapping changes were propperly implemneted, infact staff
and the AC work closely to ensure this happened correctly.
