I thought that you might have slipped up in that fashion. When I read
it, it just leaped out at me that f/(about 12) is nearer to f/11 than
to f/16 so +0.8 stops just seemed plain wrong. Glad we cleared that
up.

Stand firm for what you believe in, until and unless logic and experience
prove you wrong. Remember: when the emperor looks naked, the emperor *is*
naked, the truth and a lie are not "sort-of the same thing" and there is
no aspect, no facet, no moment of life that can't be improved with pizza.
