I think its the last part of this statement about 'paid bandwidth' which is 
the bit that may make your statistical sampling comment , but I'm unsure if 
your 'paid bandwidth' is the same as the one thats in my head.

In general (minus 'paid bandwidth' and taking the view that all bytes 
passed between the customer and the provider have the same billable value) 
byte transferred systems are more reliable if you take as your yardstick of 
'reliability' that the same algorithm applied to the same raw data should 
yield the same result. As long as both parties can agree (precisely) when 
the measurement interval starts and stops, of course.

Of course if you then want to complicate the picture by attaching different 
billing rates to different packets, then once more the complexity rises and 
the accuracy tends to drop.
