(As a percentage of the address space, not a percentage of the number  
of blocks.)

And that's with IPv4, where you have to show you really need a block  
of 256 addresses to qualify for a PI block. In IPv6, that hurdle has  
been removed so it has the potential to see even larger numbers of PI  
as soon as IPv6 deployment starts taking off.
