After 3 hours of using Focal, shooting test patterns and going through charts I have the 70-200 at +7 wide (70mm) and + 5 at Zoom (200) on the one 1DX.

However, it's not as sharp as when I put the lens on my 7D and the 70-200 is set to 0.

Go figure! No amount of MA tweaking gets the 70-200 as sharp on the 1DX as on the 7D

Try putting the camera on a tripod, turn off IS, then use live view at 10x magnification to focus on a test chart manually. Even better is to use 10x LV in conjunction with an app like DSLR Controller on your phone/tablet or equivalent on your PC - that way you can step the focus motor in tiny increments without having to touch the camera or lens at all. If you can't get that to be sharp then there's definitely something wrong with either the camera or the lens.
