Keith, any embarrassment I'm potentially suffering is dwarfed by the ridiculousness of you asking ET for advice on the original question. As I have said, would you ask your car mechanic about issues you are having with your home plumbing? It's ridiculous Keith, and so are you. I have given you my opinion on the OP. If you choose not to accept it, that's your problem not mine. I'm confident you should not be giving any advice, free or otherwise, since you claim to be a tech professional but you can't form an opinion to answer any of the 4 prompts above.
