Henry, you are GOOD humor! I laugh out loud every time I read your posts. Tolerance is not your virtue. As a "noob" to the 911, I fully agree with your "experience" statement. I practiced the assembly of my case four times prior to sealing it just to make sure I had the process straight in my head. I have never done a 911 and it is all new to me except similarities to some motorcycle stuff from the past which I draw on for my comment.
Just my two cents worth on the case sealer that I don't think anyone mentioned is that there needs to be material applied to the main webs not only to "glue them together" but also keep the clamped dimensions square. If you put the sealer on the perimeter only and not the webs, the case would end up distorted because the webs would be drawn closer to the crank center-line than the perimeter sealing surfaces. Since both case halves are machined flat with all contacting surfaces even, sealant must be applied to ALL surfaces to keep the case halves square to one another when torqued. I'm sure it can only be measured in thousandths of an inch, but measured never the less.
