Because of this policy ISP's should start getting allocations from
the InterNIC as soon as possible. If you get allocations from another
provider, you don't gain any history with the InterNIC. All of
that history goes to the provider's allocations, not yours. When
you outgrow a provider (and the provider's provider), and later
go to the InterNIC, you start over again with 'slow start.'
No, this isn't necessarily true. Many providers assume that just
because they received a /19 or whatever from its upstream ISP they
will automatically receive a larger block from the InterNIC with
no questions asked. ISPs must show they've utilized any previously
allocated blocks (whether from the InterNIC or from its upstream)
efficiently to receive additional addresses. Once they do this
than there's no problem receiving additional space. If they have
not shown proper utilization than in some cases they will receive
a smaller block to start.
