George,  while I wouldn't say too much about the Stereo Graphic, I can say
that, in the case where one uses a pair of long lenses in a twin-SLR-rig
set-up and you are wanting to stretch the depth-of-field (dof) a little, it
DOES help if you set one lens a little in front of your chosen dof setting
and the other a little behind same.  While it is probably question of
degree, one would need to experiment.  However, in my case, I guess I
haven't pushed my luck too far but I can say that there is validity to the
theory.  For some reason, the brain appears to "read" the sharper version to
a higher degree than the other.
