I believe this assumption is false.

Section 4.2.4 of the NRPM covers ISP's returning for additional
space, which I believe is the most relevant section here.  Note
that end users and an ISP's very first request to ARIN have different
criteria.

http://www.arin.net/policy/nrpm.html#four24

  4.2.4.4. Twelve months

  After an organization has been a subscriber member of ARIN for one year,
  they may choose to request up to a 12 month supply of IP addresses.

Also note this was just changed to 12 months by proposal 2007-22
(http://www.arin.net/policy/proposals/2007_22.html).

Anyway, if ARIN is allocating the correct size blocks all ISP's
have been returning to ARIN approximately once every six months,
and will now be returning to ARIN approximately once every twelve
months.  The size of the allocation should have no real bearing on
this situation.
