Amazing. Thanks for doing the numbers!
And yes, there are some large /8s, and public space is perhaps not
really indicative of number of end-hosts, etc, but even so, I think it
is a very interesting statistic to have, in addition to the
(pessimistic) 16.6% number.
We still have the last big problem with access enablement (how many
NRENs have member universities with access-enabled IPv6?), and CPEs.
