I see it in the Library module sometimes due the quality of the previews but I haven't really noticed anything in Development or when printing. Out of interest does the Camera Calibration Profile make any difference ? I know a couple of the Nikon profiles that do bad stuff in the shadows.

Are you talking about the edges of the blue patch? I suspect Fill Light may be the major contributor -- it works on a mask, and you can sometimes detect the edges of the mask, which could appear similar to posterization. Do you see it if you back off on Fill Light?

Fill light made minimal impact. The 3 biggest contributers were the tone curve, contrast slider and brightness slider.

I should have clarified about the images in dropbox.

There are 5 jpeg images and 4 screen shots with develop settings.

DNG - default LR import settings
Capture1 and the resultant jpeg 'one'
Capture2 and the resultant jpeg 'two'
Capture3 and the resultant jpeg 'three'
Capture4 and the resultant jpeg 'four'
