I'd be wary of getting in to using an "average number of bits" in this 
calculation. By definition, an "average" is already calculated over a 
period of time. We are then dividing it by a further component of time.

I'd keep it simple by just saying:

Throughput (bps) = total number of bits transferred / time in seconds

As John says though, including large quiet periods in the selected
time period may adversely affect the result you're after.

Customers generally accept the definition as being the raw bandwidth
capacity of a link, unless otherwise specified. If a customer has specific
application-layer throughput requirements then this is normally specified.
