I think you didn't understand what I was getting at as people not being in line shouldn't effect it. In all honesty outside Express/Reception Area, no one should be standing in line longer than 10 minutes. Let me paint a picture because that was the easiest one I can think of to demonstrate my point. Each waiting area acts as an attraction in its on right and would have the ability to be bypassed depending on levels. It also helps even out the Express/Standby Numbers because Standby will actively have things to do for at least 40 minutes while Express bypasses that which will help out with the Standby vs Express distribution. I will paint an example using an IP underneath. It pretty much just a combination of Fallon, Gringotts, what Universal is doing with some of their temporary attractions in Japan, and the rumoured Star Wars attraction queue.
