I have to disagree here. 10% of the requests are for 90% of the 170 -  
200 million IPv4 addresses given out per year. These are going to  
large broadband ISPs in blocks of a quarter million or (much) larger,  
upto /8. At some point, the RIRs will be out of large enough blocks  
to satisfy these requests. Nothing to be done about that.

The decrease over time / address market stuff only applies to the 90%  
of requests for very smal blocks that together only use 17 - 20  
million addresses per year. Those can be satisfied from reclaimed  
address space for years to come.
