Look for the mail by alain.bidron at francetelecom.com with the subject
"HD ratio policy proposal"

In the mail is a formal proposal entitled
"IPv4-HD-Ratio"

which has the key sentence
"The proposed value of the HD ratio for IPv4 is 0.96"

As you see the HD Ratio propsed is much higher but
would help LIR's with bigger allocations to justify
their IP usage.
