Good question...

Heres a table of the ratio of total address allocations using the RIPE NCC 
data, comparing the address consumption under the current 80% utilization 
criteria with a number of values for an HD Ratio criteria. I've included 
the mean standard deviation to give you a sense of the stability of these 
results. (Again, the technique here is to conduct an "experiment" 
consisting of 1000 separate simulations of a batch of 10,000 allocations, 
and the "result" is the ratio of the address space allocated under an HD 
Ratio framework, as compared to the same simulated end use populations 
being served under the current fixed 80% criteria)

(fixed width font may help here)

HD Ratio Ratio Mean Std Dev
0.98 1.04868 0.02285
0.97 1.25899 0.03363
0.96 1.45854 0.03371
0.95 1.63073 0.02848
0.94 1.78332 0.01859
