"But , for starters, something simple, straight forward, easily achieved.... if I could demonstrate to you two, to your satisfaction"
but Kevin, we lack your "faith" so if the demo leaves open the possibility of alternative explanations for your success, you will take it as vindication and we will take it as inconclusive, i.e. a bit of a waste of time. It's the way it is I'm afraid. Half a test is no better than none.
