David:
    I think my prior response answers most of this, but it should be clear
that the 25%-50% "suggestion" can't be compatible with the 80%
requirement. These must be refering to two totally different things,
particlulary because the 50% referes to a year, and RFC2050 suggests 3
month worth of IP address for subsequent allocations.
