That is a very old and expired personal draft, not an IETF document. Very dangerous
to rely on such a document. It was eventually replaced by a working group draft
http://tools.ietf.org/html/draft-ietf-v6ops-dc-ipv6-01#section-2.5.4
but that has not been accepted to become an RFC and has also expired
after an unsuccessful WG Last Call.

(You can always check the status of an Internet-Draft at
https://datatracker.ietf.org/doc/ .)

But in any case, look at the full context:
   Depending of the complexity of the DC network, provisioning and other
   factors we estimate that the extra costs (and later savings) may be
   around between 15 to 20%.

Note the parenthesis!
