Math? What does math have to do with it? *grin*
Oh well, I guess there's some math there but I find it hard to believe 
that out of 50 address requests per week from ISP's there are more than 
10 that are truly clueful ISP's that absolutely need a /16 one year down 
the road.

There are still a *LOT* of people that think the Internic hands out 
portable addresses and startup ISP's are not much different from the 
general population in that regard.

Besides, the process of applying for an IP block is a lot like a 
negotiation. The newbie ISP presents their case as to why they know they 
will be mega-ISP Inc. a year down the road and absolutely must have that 
/16 block from the Internic. Then the Internic can counter and ask why 
they can't just use RFC 1918 addresses and run a NAT on their gateway. 
The ISP can plead poverty that they cannot afford to buy a PIX from Cisco 
and then the Internic can point out that a poverty-stricken ISP isn't 
likely to need a /16 and counter with a /23. And so on ........

It is by no means certain that IPv6 will ever be deployed. There are lots 
of ways to wring new life out of IPv4.
