If a gun can be weighed to with in a standard of say an ounce, or a balance point measured to say within a quarter inch, is it accurate enough to say mounted swing effort is near the butt?

Will different shooter builds, shooting styles and target presentations have the potential to significantly change the mounted point of rotation in a consistent way for some shooters and in a variable way for other shooters and situations?

There are probably ways to measure a gun, but are there predictable ways to determine how it will be guided through space by a human, meaning are fixed dynamics a predictor for a successful wing shot?
