how is server usage calculated?

I recently got a block account so I have been noticing the server bandwith measurements more closely and there is a discrepancy between the total bandwith measured by SAB and what the provider is reporting. Currently SAB claims 66 GB total and the provider claims 71 GB.
So my question is if SAB measuring the Usenet data downloaded or the file data written to disc?
Or any other suggestions of why there is a significant difference (5 GB is 7% of 71 GB).
BTW, I am only using the block account on SAB on one PC.

We measure the exact number of bytes that we receive from the server on the socket. Maybe they used a different start-of-measurement date?

There's also some lower-level packet retrying going-on that won't be counted by SABnzbd. I'm pretty sure service providers count it though.

Thanks for confirming that SAB counts what it downloads not what it writes out.
The block account is new and I have only used it on a single PC/SAB so I doubt it's a when they started measuring issue.
Maybe something like what OneCD suggests. I'll keep checking at intervals to see if the 7% stays consistent and I'll probably ask the provider as well.
