download meter?

[metakinetic]

I've been happily using altbinz 0.24.2, but I'd like to know how accurate the 'Transfered Bytes' meter is.

I've been purchasing block accounts, and always seem to end up short. On the last 100 gb block I zeroed the altbinz meter. Now according to the usenet-news site, I have overrun my allotment by almost one gb -- yet the altbinz meter shows only 96,575.72 mb (or 94.31gb).

Usenet-news advertises that they meter block account traffic at 90% (their way of dealing with not charging for headers without actually measuring them) so I figure it should allow 111.11 gb total download [.9x=100gb] or at least 110 gb if they really just tack on ten percent.)

IAE, I find myself on the short end of at least a 16 gb discrepancy, similar to what I've noticed before. It seems to me that the figures should be a lot closer. Has anyone else noticed this? Is there a reasonable explanation?

Do they only monitor the download traffic? Because there is always some upload for verifying packages. And there is always some overhead in the download.

I checked the site and faq and they don't mention upload overhead for verifying download packages. Do you know what sort of percentage this overhead might typically eat up?

It would also be helpful to know if the altbinz 'Transfered Bytes' figure includes this overhead.
