Couple of points.
(a) the net to gross margin doesn't give you much fat to play with near the departure end of the runway (depends on which case is limiting and how limiting the runway is) but provides a significant margin by the time you get to the fourth segment particularly.
(b) no reason why you can't have several procedures for one runway based on whatever criteria a particular operator considers important or appropriate .. only depends on how much work the operator wants to pay for.
