That was my impression, but I wasn't 100% sure.

I think they are OK, there is always a little arbitrariness to these
things.

Actually I've been trying very hard not to limit or preserve IPv4
at all. I'm mostly tring to make it so most groups run out about
the same time, within 3 months or so and try to make sure that
the last bits of address space get spread out among multiple
groups.
I agree with not wanting to do anything to really preserve IPv4,
but some really nasty things can happen in the Internet market
place if we don't think about how we Run-Out of IPv4.
I don't want to or even think we can prevent Run-Out, but I do
want some order to the Run-Out.
Since you brought up Soft-Landing, I'll use an airplane
analogy, we are going to crash, not a hard landing, a real
honest to goodness crash. But, do we want to auger in, or try
for a belly landing on the water. Will we be United 93 on 9/11
in Pennsylvania or USAir 1549 last January on the Hudson
River in New York?
So we are going to crash I just want it to be one that most of us
will walk a way from.

I agree, I just want to bring a little order to the event.

I'm not sure it is incompatable with the other two proposals or
even my goals for them. I was just try to get your view.

I think your general idea is a good one, it just need work on the
details. It is dealing with the one of the parameters I didn't
touch, minimum allocation size. But in my "Predictable IPv4
Run Out by Allocation Window" proposal, I did allow for the
idea we might change the minimum allocation size. And I think
it might be a good idea, but probablly not until the last /8 is
received.
