You’re just arguing at this point. The scores I’m talking about are not arbitrary, there are a few standardized measures used in social presence research to attempt to make apples to apples comparisons between communications tools attempting to compete with f2f. The point is that the scores people give are literally asking users to convey their feeling that the experience met the baseline of face to face, or not, along various dimensions. You sound like you have an axe to grind, and aren’t actually looking to understand anything new here.
