You're assuming a single focus here, and it has a dual focus.  Apply
this assuming, as was the given, that the planet is orbiting TWO foci,
both binaries.  It does more than drift away from one, it drifts TOWARD
another!  Similarly, it is not in a sedate orbit around one, it is
approaching in a comet like fashion, moving more directly TOWARD it's
suns when it makes a passage past one or the other of its foci.  Allow
for increased speed at those times.

Remember, Jim Scotti stated that a planet CAN orbit BOTH suns in a
binary system.

You went through an elaborate statement to say you base your theories
on orbits upon what you have OBSERVED - inverse square on Gravity and
momentum conservation of energy rules.  Bearing in mind that you have
not OBSERVED a planet orbiting two suns, both suns in a binary system,
what would that orbit look like?  For the sake of moving this argument
forward, we will assume for the moment that your orbital mechanics are
correct, and not under challenge.  Just paint for us what that orbit
would look like.  Not the several pages of math, but just something
simple, in the manner you are so very skilled at employing.  A simple
verbal description of what such an orbit would look like.  

You have a head start in that your astronomy computer programs already
ASSUME a second foci in elliptical orbits.  Just put that foci out
there, WAY out there, some 18.724 times as far as Pluto is from your
Sun.  Assume the same factors published prior to the search for Planet
X, Van Flandern's statement that the perterbations observed in the
outer planets would require a planet or brown dwarf 2 to 5 times as
large as Earth.  We are requesting for this discussion that you assume
a planet 4 times as large as Earth, as this is our statement.  Grant us
this assumption in return for our granting you that YOUR assumption on
orbital mechanics is correct, tit for tat, one concession for another,
and since both assumptions as based on human assumption, you should
have no objections.  This hypothetical discussion would be no different
from any other occuring on sci.astro in that regard, applying known
physics, as you say, to a hypothetical situation.

What would such an orbit, where a planet orbited both suns in a binary
system, look like?
