At least those numbers make sense - your other tool must have been 
reporting deltas.  I'm not sure what controls the update rate - I 
usually work with things that track 5 minute samples and haven't worried 
much about smaller granularity.  Since you are counting bits, it all 
averages out the same anyway when you add in the time factor.
