My tests demonstrated this to be the case only when Tri-X was printed with 
an enlarger that had diffuse illumination.

More germane to this mailing list: highlight separation may be similar to 
my silver-print tests when black-and-white film is scanned using a scanner 
with diffuse illumination such as the medium-format Polaroid/Microtek 
scanners. The Nikon scanners, in particular, use a collimated light source 
and should therefore provide highlight separation similar to that of a 
condenser enlarger.
