Please say the exact settings you would have preferred him to use (shutter speed/f-stop/iso). The only way he would get cleaner shadows is by trading off for highlights.
I have done that already in my first response in the thread. But I will sum it up again if you like.
As I said earlier I already know that with D600 I can always collect double the light if I choose its lower iso setting, relative to D700, and half the shutter speed. I was more interested to see how they compare in a different scenario when the light is the same. Imagine the cameras handheld in the room in the OP.

Are you aware that your conditions are impossible? The D700 already has more clipped highlights than the D600 at half the shutter speed. If you double that to 1 second, you're going to have even more clipped highlights in the D700 photo. The fact that you specify the exact exposure in steps 1 & 2 and then say in step 3 to expose for the highlights doesn't make any sense. Perhaps you mean that step 3 is a post processing adjustment, but he's already at -100 for highlights. Those clipped highlights are very much clipped, and doubling the exposure is going to make it worse.
I can understand wanting to see them compared at identical exposures, but comparing the maximum dynamic range of each camera is also a useful test.
The shutter speed can be any shutter speed. The only requirement for the exposure is to place the D700 highlights as far to the right as possible without clipping. Then use the same exposure for the D600. Why is that impossible?
