Lou, I think you are a pro. Yes, I know, you are actually.

That's a nice description and I have to try all this and also take back my comment on the "the gauge will always be happy" systems modelling since this stuff actually is modelled.
Now I know how to take those "T" signs too. Great!
Also great is the detail of the CS planes then, best to be enjoyed with some explanations from you because otherwise the laymen's eyes of mine may miss them.
