Yes I have used Carl¹s curves and I am not looking for something
exceptionally different. I am trying to get under the hood of QTR so that I
am not so dependent on others, such as Carl, to provide their curves for
various ink and paper (and spray) combinations.  For example, Carl had not
redone his HPR curves for the new release.  (If for example I switch to
using Eboni instead of UC MK, or wish to try other papers, I don¹t want to
have to bug Carl or anyone for curves.)  I thought a good place to start
would be to try to replicate Carl¹s work for, say, EEM so that I had a check
on my work.  I have been trying to understand what drives the ink limit
figures (generally and vs the documentation) and furthermore puzzled by the
differences I have found in partitioning figures even when using
similar/identical ink limits.  I am not at all suggesting Carl has not done
his work well.  I have learnt a great deal but still have further to go.

Plus I guess the posted RC prints by Carl were made with the use of UC PK
and not MK.  I suspect PK is much warmer than MK (?)
