You may be right hookedon6.

Right now my 2 element quad has one feed point and shows 1.15:1 match. but when I add the 2nd feed point at the other corner the match goes to heck in a hand basket, showing 3.038:1 at port 1 and 2.88:1 at port 2. See below.

This stuff is above my level of understanding with modeling or real world, but I worked with a friend once trying to make his quad with only one driven element wire into a dual polarity setup, and when we connected the coax direct, we got bad results and when we removed one of the feed lines the match changed again, but still not good. We felt that allowed us to understand that the feed line on the opposite side affected the match, and we assumed that with the line attached in such a way, it naturally became a part of the antenna as a consequence.

I understand a little of the ideas you posted, but a little understanding is not enough. That is why I asked Homer about his attempt to do the same, but I must have misread his words.
