Your results pretty much agreed with what I've observed scanning music.
One question not answered to my satisfaction yet is "how many grey levels
is enough?" I've got a suspicion that as litttle as 4 may be perfectly
adequate most most line drawings.
If it's any comfort, the Library of Congress seems to agree with your
findings, but they tend to be split over reserving grey scale scanning for
things like pictorial and cover art and leave musical scores as B&W.
However, that's only in one collection--other collections scan everything
in greyscale. But TIFF is the file format.
