Hi Lyman
You have spent a great amount of time discussing the missing spacer and the possible consequences of it's absence. It may be helpful if you could collect all your thoughts together in one post. I think in doing so, it can be taken for granted that you think the missing spacer is of importance, so for clarity sake it may be wise not to repeat your detailed analysis of that absence, but instead concentrate on it's relevance to the final outcome.
