Nnngh. Thanks David and Mikael. (This is why you should never write
e-mails while not under the influence of coffee, kids.)

Anyway this part needs corrections (emphasised with **) too:

I'm assuming here an allocation rate of ~0.3 /8s per month, cf.

Probably this estimate is way too low though, due to the unmet demand
that has been building up in the LIRs over the course of the last four
years. My guess is that we'd easily manage to fully deplete the first
240/4 IANA->RIR tranche (containing a /7) before the six months have
passed before the second tranche (containing a /8) comes, and so on
until the IANA recovered IPv4 pool is all gone.
