The logic (Yorkshire style) where a shorter (same) runway gives a greater RTOW than a longer (same) runway seems to defy common sense. It could only be a number crunching game that only a computer could devise. I'd be delighted to read a full explanation because my brain does not compute that idea.
My TomTom tells me that route A is faster (not necessarily shorter) than route B. But I know that from experience that not to be the case; at least at certain times of day. Equally I know that the 'short-cut' through the housing estate with speed bumps is definitely not the quickest. It might be the shorter by 200m, but hey, it's a computer number cruncher.
