I think it serves when you have two airspaces with no margin between them.
For exampple, one is 12/SFC, the other is 70/12+. So at 1200 feet you're in
one airspace, and at 1201 feet, you're in the other. If they were specified
as 11/SFC and 70/12, the space between 1101 feet and 1199 feet inclusive would
be outside either airspace.

Wrong. Study the TERPS. Again, Anthony, you're a simulator freak, not a
pilot of any kind. Your posting of incorrect and misleading answers is a
waste of everyone's time. What you "think" is irrelevant.
