Bandwidth caluation, overcharge?

Hi All,

I have my own dedicated server. My ISP use a formula to caluate my bandwidth :

(avg. in) + (avg. out) / 8 (bits) x 60 (seconds) x 60 (minutes) x 24 (hours) x 30.5 (days) = Total Bandwidth

When I looked at my own stats report (AWStats http://awstats.sourceforge.net/), the total bandwidth is around 350GB. But my ISP MRTG report shows that I have around 700GB total bandwidth for that month.

I would like to know will there such a great differences between MRTG and AWStats? There might be a differences but I don't think there is 100% differences.

I would also like to know does ISP usually caluate incoming traffic (upload, incoming hits...) ?

Any comments are welcome.

Max
