And my experience is that European workflows use the Perceptual table almost
exclusively when preforming file conversions, while in the US the Relative
Colorimetric table is used more often for file conversion than in Europe,
especially where precise color values are expected (conversions for proofing are not
being described here). This fact, taken in conjunction with your observations
about the table values, might be one factor in the differences of opinion we
are hearing.
Keep in mind as well, that these profile's actual conversion tables were sort
of reverse engineered to match the existing v1 profiles, that offered good
previews, but were not designed for use in seperating files for press...
