I'm obviously a bit simple...
ME 18 (or 20) is what exactly?
Where does the nomenclature come from?
There must be a manual or text or rule book I'm missing here.
As for over complicating the issue, I have no idea how complex or simple it should/could/must be.
That's why I suggested we get on the front foot and put something in place after the expo dust has settled.
Glad it is being addressed, though...Blackhawk, you sound like a knowledgeable resource.
