A very good technical point.

There seems to be a lack of harmony though.  An "end user" who
receives space from their upstream must show the same 80% as their
upstream ISP (see http://www.arin.net/policy/ipv4.html#reassign).
An "end user" who goes directly to ARIN can use the 25%/50% rule.

Is there a reason to hold the same end user to different criteria
based on who they ask?  Could this issue be solved by making the
25%/50% rule apply to downstream customers of an ISP, or by making
"end users" who request from ARIN use the same 80% rule?
