I was referring to the the relative colorimetric table.

I didn't try generating a perceptual table and seeing if
it behaved similarly or differently. I suspect it
may be better for the reasons you state above, but
may still not perfectly hit the black point.
Part of the reason is that the black point is
a sharp cone shape providing a smaller target,
and amplifying any inaccuracy.
