P3D horizontal projection adjustment

[pebaker@xxxxxxxxxx (Paul E Baker)]

Apart from the fact that slight vertical adjustment is usually always
needed when running slides mounted in different brands of mounts, I
like the idea of not adjusting the projector during competition.  But
I have a question on the horizontals:  Is there a "correct" way to
adjust them if to be left alone afterward?  Sometimes I adjust to
overlap a bright spot in a particular slide when the contrast is high,
to minimize ghosting.  Otherwise I tend to always adjust so the windows
overlap EXACTLY, for two reasons:  I feel the window should be in the
plane of the screen, and when there's intentional "through-the-window"
effect this is the way to maximize it.  But most others in my club seem
to try to go 50/50 on the horizontals, between the window and a distant
point, which frankly I don't understand and don't feel produces the best
presentation.  So, what the "correct" way?
