QTR-Quadtone RIP

I have a confession to make.  I have an i1 Photo, and have been taking
existing curves and setting the black limit, repartitioning the inks
and linearising the curves without any real problems.  But I have
baulked at making new curves from scratch.  Doing all this warm and
cool adjustment seemed like too much trouble and required too much
judgement.

Now, I'm considering getting some Piezography inks, and I can't seem
to locate curves for some of the papers that I want to use, e.g. VFA.
 Then I realised that because these K7 inks don't allow you to adjust
the tone (for a given inkset), all I need to do is set the black
limit, repartition and linearise.

Is this correct?
