OK, got it. But my reasoning was "if PY151 gives me a neutral black at a
specific proportion to M and C - also keeping the constant the proportions
of M and C to each other, then, since I'm calibrating all colors
separately so that they give same luminosity on print, for the same gray
value on screen, they should continue to give me neutral colors on the
step tablet test when I print them on top of each other"... Maybe it's a
too long / complicated sentence but I hope it describes well my approach.
Will definitely print the colors together, to decide and see how much they
have to be diluted for a good tricolor print...

I agree, since I too have experienced this. What I'm trying here is doing
it in a more controlled fashion, and to get (maybe marginally!) better
shadow and hightlight detail. I have to do it as precise/controlled
fashion as it can be at first, to be able to work in a free / intuitional
style later. Just like in learning painting, you can't (or shouldn't) go
directly to abstract painting without first climbing the classical

Believe me I'm not trying to get it more complicated than what it is ->
just want to settle on a simple style based on experience with complicated
test / working procedures...
