[arin-ppml] Policy to remove 25% in 30 days language

I think this is a good approach.

I also think we also need to recognize in the problem statement that, by
the time any new policy is adopted, almost everyone qualifying for space
under NRPM 4 will be getting it via transfer.  And in a world where
addresses are being obtained on the transfer market, strict constraints on
how quickly addresses must be used probably make less sense than they did
when most addresses were obtained via the free pool.
