Understood, thanks.  To be honest, I'm not interested enough to put
that kind of effort into it.  I just wanted to see what would happen
if I put the print in the sun, so I did it.  That's all there was to
it, no grand design or intent to create a scientific test or body of
data.  I'm delighted that prints with my favorite ink/paper can
withstand 100 hours, and logging the exposure time is pretty much the
limit of my scientific patience.  I am curious as to what at point
further deterioration will appear, so I'm continuing the test (the
print got 7 cloudless hours today).

Isn't that other testing web site that Harold mentioned doing
something like that?

Regards,
Clayton
