Yes, of course I have. All that I was trying to say is
that it's not a simple linear relationship. 
By the way, have you seen a 35mm Kodachrome projected
"way big" with a Leica projector? Seems like you can
walk right into it....

Now, let's see, where can I get an 8x10 projector to
compare....

What you gain is mostly smoother tones, not

of MTF curves, this is nonsense. Have you LOOKED at a
16x20 enlargement of a 4x5 negative? Or better still,
an 8x10 contact print? All you have to do is look!
