I think that the "Tindemans script" has more options than the "Fors script". There is also an issue that there is some variations in the Xrite Color Checker (what used to be MBCC) itself.
The DNG profiler lets you adjust color for each patch individually, I think. As far as I understand you can have some kind of automatic optimization but I think you can do a final tuning by hand. I have not done it myself. See attached screendump.
You also need to consider color spaces. If you do things by the numbers I guess LAB is what is needed. If you use perceptual rendering the colors will be shifted around when you convert between color spaces, so you probably need to work in relative colorimetric. Sorry for mentioning this, I'm sure you already paid consideration to this, but the information may be useful for some other reader.
the Fors scripting is what I used before the release of the DNG profiler.
That is what I am using to generate the base camera profile.
The result is an image that is reasonably accurate but well short of the accuracy that I am looking for. As was the Fors script. It was after using that script that I used the selective color and curves layers for fine tuning.
Now I am looking for a way to do the fine tuning in LightRoom.
