George,
What bothers me about your "analysis" and last e-mail?
1. Your previously defined attitude about the A-T's:
On 1995 August 19, Kevin asked you a simple question about the A-T's and
you responded on 1995 August 20 with, "No real radiant...probably best to
not favor any possible radiant at this stage." Considering that on the
latter date you also wrote to Marco Langbroek and wrote, "I really don't
know too much about this possible radiant," it would seem you were not in
a position to judge the radiant that way. Considering that extensive
articles were written about this stream and published in WGN and Meteor
News, you need to do a little more reading on a subject instead of
winging it.
2. Your "Scientific" Method:
I am writing this at work and your response to me last night is currently
at home, but I believe you mentioned something along the lines of maybe I
was wishing too hard for the A-T's to be real and something about my
scientific methods for studying this stream is not based on observations
by experienced observers.
Okay, here we go (deep breath taken here, considering much of what
follows was withheld yesterday because I did not want to cause problems).
Velocity questions:
Those obtained for the Xi Draconids were exorbitant.
Radiant questions:

Kronk next searched through another extensive list of radiants that had
been compiled by Cuno Hoffmeister in his 1948 book Meteorstrome. The
following radiants were extracted.
