Unless I'm missing something, it will double the size of it, since that
/24 out of that /8 won't aggregate with their other address space.
(Hint - our AS has 198.82/16 and 128.173/16 and some other small blocks -
how many routes do YOU see for us?)

Also, there's no real reason to think that address space usage in that
bootstrap /24 will accurately reflect usage in a /20 allocated to them,
since THAT /20 will probably be sub-allocated to users/customers.  Heck,
in our AS, the nameservers and mailservers and the like would probably
fit into a /27 (maybe a /26), and wouldn't tell you anything about
the /20 that covers Torgeson Hall....
