Steve, nothing in my argument requires the real world to be like a lab 
Please don’t start seeing ivory towers where there are none. I can assure you I live in a regular house made of brick.
I do understand that and I have read that thread recently (though I was not reading the forum actively when it was originally posted). I am just offering up a pursuasive argument for whatever it might be worth to anyone (or not).
Also, just because Michael Harris has made his mind up, does not mean that the rest of the readers of the forum have, so regardless of whether the company owner cares to hear an opposing view, others may be interested in it.
