why do you think everyone shoots RAW and sharpens as part of their post
processing? they really ought to be using a proper deblur filter instead of
Unsharp Mask, but until Photoshop CS2, you had to pay extra for one.

I think it still proves something, but not as dramatically. It proves
that
the best sharpness you can get is already 62.5% to the threshold of
unsharpness. Recovering that loss of sharpness in post capture processing
will sharpen some details that were imaged by the lens as out of focus, I
believe. I can't quantify by how much, because I don't remember off the
top
of my head what CoC that a typical good lens can record on film when
critically focused.
