All valid points OMA.
From a pilot's viewpoint, just a small observation.
Please remember that ROT(Runway Occupancy Time) is NOT always a function of the exit an airplane takes.
An airplane could take the LAST exit on a runway(therby saving brake pads) and still vacate the runway in less time than another airplane which takes maybe 2-3 exits before the last one.
It's all a matter of variable decelleration.
As a matter of fact variable decelleration combined with a slightly varying touchdown point can give an airplane some of the shortest possible ROT's possible.
This is just because a lot of times the ATC feel the pilot is not expediting vacation just because he is using the last exit. Not so. As I have attempted to explain above.
