Having put on a seminar or two and having answered phone calls and PMs and emails I am fairly confident that if Miles puts on a seminar he should limit the discussion to an outline of what spare parts are available, what intellectual materials are available and a general overview of the salient points of the CC electronics and the coach systems. Specific questions after the presentation will fill the voids.
All of us, me included, may learn about the details of something, but we forget it before the sun goes down. It is only important if we are having problems with the system being taugh when it is being taught.
But what we retain and will always be able to use is the knowledge of what's avaialble and where to get the parts and information required.
