Roy,
I wasn't too clear, but I have 2 T networks back/back. That makes the center
cap C/2. I am going to run SWCad on the Pi configuration later, and see what
that does.

If you've cascaded two sections, you have two 1000 pF capacitors in
parallel at the center. That makes a total value of 2000 pF at that point.
