Having said the above, as Dr. Luigi Fontana says (one eminent longevity expert), we have no biomarkers for EAAs or protein, so we really don't know what's the better amount for longevity.
Another basic aspect is that the optimum amount for longevity is different for different people, according to genotype, activity, exercise, diet and so on.
It appears that you have lost your enthusiasm for the very low use of protein while aging. I recall articles you produced that suggested as we grow older protein is no longer needed as it was when we were young and still growing muscles and bone structure. In fact that too much protein while aging had a deleterious impact on aging.
