What are you talking about? You literally stated that this-
Which are objectively, and demonstrably false.
No. In most of those, specifically all from Martin L. Fackler, Dr Gary K Roberts, Duncan McPherson, and the FBI- they specifically do state that “ft-lbs” of energy is not a wounding mechanism, does not and can not tell you how deep a wound will be, how wide, nor the shape of it. It is functionally a useless metric as those I pictures I just posted show. You can’t tell which did which.
If nearly 4,000ft-lbs of energy and sub 400ft-lbs of energy are creating nearly identical wounds, clearly it isn’t the amount of energy that is the differentiator.
