	Pretty much every billing scheme is based upon statistical sampling in some
form. It's not exactly fair to ignore sampling errors in your favor and then
cry foul should the odds go against you. On the other hand, providers that
use statistical sampling should disclose that to their customers so that
they understand that they're being billed using systems that aren't
necessarily 100% reproducible.
