Their "apparent" dynamic range is equal...since you haven't hit a wall with
either.  Correct that if the dMax - dMin of the silver print is a higher
number, the density range is greater.

Right, but the proper term is density range, NOT dynamic range.

Exactly.

Why, Dynamic Range, of course ;-)  That's why the word "dynamic" is
used...which basically means "of or relating to variation of intensity" in
this use.

BTW, this stuff is just so important to a deeper understanding of quite a
lot of stuff in photography, much less other things in life.  At least in my
opinion.

BTW2, did my explanation of your A vs B question answer the question?
And...your "Z's" are done ;-)
