Actually from my upstream ISP (UUNET) many years ago.  I was requesting
a /21.  The requirements were essentially the same back then.

You're requesting 4K addresses.  They want to know that 1K will be used
right now and that at least 2K will be in use within a year.  If the
only way you can use up that number of addresses is by allocating one
thousand /30's they will turn you down.  They are basically looking for
individual addresses, but you can count the lost addresses from your
subnet scheme.

It sounds like you want to have a fairly generously sized subnet for
each group, but the groups are too small to meet the utilization levels
(25%, growing to 50%).  If it is just a matter of a bit more time and
growth, I'd show them how you'll exceed 50% in 18 months (or whatever)
and hope for the best.  Otherwise you may need to reduce your request

I had not realized that ARIN was still distributing addresses.  I had
thought they had pretty much given them all out.
