Hmm... I have mailed another mail which gives my scenario. I paster here
FYI.

As Grant Taylor said, there is a leverage. And from above explanation, I
have to figure out how much bandwidth we could save if we have large
list users.
Let take 1000 user for example, how can I estimate the bandwidth I
saved?
