So you are suggesting that each RIR would have its free pool fixed by someone else. What precludes an RIR from determining its remaining free pool at some point and declining to request any more IPv4 address space from IANA. Planning for the depletion of the RIR pool and the policies required to administer the IPv4 space in its region after the depletion of the free space to support its current policies is a much more important and serious issue than this effort in trying to decide the value of N and everything else about these policies. The efforts of each RIR should be directed to their own situation before playing around with the IANA pool.
