I had one of those seats on 03/27/17. The Even More Speed was not a big advantage at the Orlando airport. It means you go in a different line to get to the TSA agent who checks your boarding pass and ID. The regular lines were just as short as the Even More Speed line, and the TSA guy was alternating between lines. So no advantage there at that particular time.
Once you get past the guy who checks your ID, the Even More Speed line merges with the other lines to get to the point where your stuff goes through the x-ray machine. So Even More Speed is no help at that point.
