[AusNOG] Average Usage Per Service

[Narelle]

In my experience the usage of a retail customer was directly proportional
to the overall international bandwidth available to the network. ie total
capacity divided by the number of users

No matter how many times I did the maths, it always ended up about that...
I'll be very surprised when that changes.
