True. The first two tests I have received were simple. But I'm not sure
what the point of these tests are if the results aren't deemed to be
indicative of anything. I propose that we skip straight to tests that
actually determine whether I can detect these "undetectable" messages or
not.

I propose that you (or anyone) send me two images: one that contains an
"undetectable" message, and one that does not. I will try to detect which
is which. The images do not have to be similar.
