I might have misled you :-(  Colleague Tom Yoksas (who's been monitoring this
exchange) pointed-out that most of your smaller-volume feeds are coming from 
marconi.rwic.und.edu and not from us.  The exception is the GPS feed, whose
interpretation is problematical.  As a consequence, we can't say for certain
that the flow from us to you is being shaped.  :-(

Because the CONDUIT feed has greater volume than the NEXRAD2 feed, if
packet shaping were occurring, then that feed would also be affected.

I suggest trying an experiment.  Replace the REQUEST for IDS|DDPLUS data
from Marconi with one to idd.unidata.ucar.edu.  That way you'll get
both high-volume and low-volume feeds from us and we'll be in a much
better position to interpret the results.
Regards,
Steve Emmerson
