What am I missing? 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. Graeme Gill.
