P3D Alignment of seperate 35mm cameras...

A while back, there was some discussion
on the proper alignment of two single 35mm cameras
to yield the best results. Until I heard this discussion
I had simply made sure that "infinity" did not come
together (let's say for the sake of example that the
exact center of the focusing screens did NOT come
together anywhere in the image, and did NOT cross
either -But that there was always some attempt at a
"space" between them.)
But I heard some people say to bring the
centers together. ....I tried this on several rolls and
the result I got was that it appeared to strain the
eyes somewhat when I put together the prints. In
addition, (even though all I did was put the object
of interest that was the furthest away in the same
place of both lenses) I noticed that some of the right
-hand camera had as much, or more of the left-hand
edge image information. Hmmmmmm. Well, I then
simply "cropped" that "extra" bit of picture info on
the right-handed image (left edge) to make sure
that the right image had LESS information on the
left-edge of it then the left camera phot had on its
left side. Presto! Everything seemed closer to
"normal" then.
The conclusion I have now come to is
that it appears to be best to make sure that if
using two seperate cameras for instantaneous
shots, that to make certain that the exact center
of each lens does not meet the other in the taking
of the photograph. -Basically, simply put a little
seperation through-out infinity. Has anyone else
encountered this and found this to be correct?
By the way, I shoot print films (25 asa)
and develop 3-1/2 x 5 prints. Then I crop them
to 3" x 4" tall each mounted on 4" x 7" cards.
Then I use them in any of the older viewers.
