Yes, of course I do.  As I said, when shooting for prints of a certain
size, I want to plan an on film deviation of a certain value before
shooting the picture - id est, set a stereobase to give me a specific on
film deviation.  But the fact remains, viewer focal length will have no
bearing on the relationship between OFD, stereobase, taking lens F.L., and
near and far points.  So why is viewer focal length in the equation for
determining OFD/Stereobase?
