I can't disagree more squishy. The CG on my planes tend to get up and move quite often. Just as I think I've got them pinned down, they pack up and go on vacation. They also tend to get offended when you use the finger method for finding them. At least when I try it, they do. On my hands, my middle fingers are the longest, so I tend to use them as the balance points when searching for CG. The problem comes when the CG looks out, and sees this method, and gets offended because it thinks I'm flipping it off. It might not come out where I can find it, for a week afterwards.
