Eh? If they took the straight average from the monthly
graph they could come up with somthing moderatly close like
(average_kbit / 8) * 60 * 60 * 24 / 1024 = Mbytes/Day
Mbytes * Days = Approx Total transfer
repeat for other direction, example on a 256K link in my network
92.9 / * 60 * 60 * 24 / 1024 * 31 = 30373.945 / 1024 = 29.662056 Gbyte Inbound Transfer
The figure is only a guestamate though and I would never use
it for billing.
BTW: They do know the difference between GigaBits and GigaBytes
right? (9.1GigaBits = 1.375GigaByte)
