Though I appreciate you telling me what my problem is, I think nothing of the sort. You seem to be the one obsessed with who has what degree. I don't think you are wrong in your analysis because you don't have a degree in this, I think you are wrong because you are wrong. Not about your stage guesses (i never really commented on those) but rather about the mechanics of how it works. I refuse to argue with you about that anymore because you have conviced yourself you are right, and truely I do not care. But, I never degraded anyone because of a lack of a degree (in my life) and I certaintly didn't start with you. If you have a problem with engineers, that's not my fault. I work and have worked with many talented people without degrees and many useless ones with them....and vice versa.
By the way, my degree is not in this either, and I never claimed it was. My degree is in mechanical engineering, and my job experience is in tool design. I defer to the many other experts in this field, degreed or not. You are not an expert, sorry, and that has nothing to do with a paper on the wall.
I propose we drop this counterproductive arguement.
