Hi Rob,
I think Cotty agreed that RAW allows for more latitude. What he wanted
me to test was my assertion (based on Adobe info) that upsizing in the
RAW converter yields better results than subsequent PhotoShop
interpolation. I'm not sure if one can see the difference, but I'll
have a look. I think a 100% monitor viewing of the interpolated images
is probably just as good as a print for this purpose.

All that is needed is two prints one with an A and one with a B on the
back.
However a test like this means little if the RAW file used for
comparison
hasn't been processed in order to optimise the image or if the scene is
comfortably accommodated in the latitude of the JPEG image or if the
printer
isn't calibrated to reproduce the whole data range that it's fed.
