BZZZZZT.  B&W films have very LOW density ranges in the overall spectrum of
density ranges of films.  You're lucky if you find a density range of near 2
from B&W print film.
===============================
This simply is not true: an examination of film characteristics in Adams'
"The Negative" for example, will show half-a-dozen examples to the contrary.
See especially Kodak Plus-X Professional treated with selenium toner.  From
the first usable density of 0.3 above Fb+F (Film base + Fog) to 2.7 the
curve is practically linear.
