My analogy would be "When planning a trip thru NYC, via Grand
Central and Penn Station, are you really interested in number of

Very much so. I spend much time sorting out just that. It makes the

lifts for every level change... Underground traIns (subway) never do, but
Railway Trains sometimes do. Hence the planning.
