Are you able to tell exactly how cricket generated the graph?

Well, assuming the values above are not exact values (~75 :),
then it's off by a factor of 7.55 which is awfully close to 8,
which could well be a bits -> bytes conversion issue.

Try and find out whether the data in your RRD files is in
bytes or bits, i'm guessing it's in bytes, and Cricket
converts is to bits as is the usage for network bandwidth
data.
You will also want to pay attention to the "Base" setting the
"Graph Options".

Hope this helps!
