Now, that is a point that I think merits discussion. We could certainly add larger categories, but since there are so few large orgs, would it really make that much difference? Should we quadruple (or more) the fees of the top few, in order to give a 5% discount to the smallest? (Those values are completely made up.) I don't know...

Not at all meant to hyperbolic. I think comparison between /16 and /20 is perfectly within the realm of normal. A hyperbolic comparison would be a /6 (which I believe is about the largest any one org has as an aggregate), versus a /24 (the smallest), which under the "same cost per IP address, would be a 26,214,400% difference versus a 1,900% difference under my example. A side effect of my example, would be more confusion due to there being potentially 20+ categories for IPv4 and 40+ for IPv6. Even if you boiled it down to an single equation, many would not understand it (*ahem* the HD-Ratio that used to be in policy for IPv6 allocations)

1,600% increase in fee for a 102,400% increase in space, sounds about right, considering the amount of work needed, is more, but not linear compared to the space.
