Mike,
you could compare the measurements with the profile output of the same
Cmyk colours. This is possible in ICC Examin with feeding the profile +
the ti3 files at once. You should then be able to select from the
main window "View"->"Quality Report".
But the relyability is a bit reduced as these values where formerly used
for profiling. A clever profiler may try to optimise for just the
measurements and pays bad for other colour areas. So take such
comparision with a grain of salt.
Better is to test with a extra set of measurements not used for profiling
and compare how these play. ICC Examin, and similiar tool, will report much
more relyable then.
