Larry, that is because I did use two turnouts connected together. The #6 is long enough to handle the entire 50' car. The #4 is to short and the car is already on the counter curve. That makes a big difference. I did use the example because ISL have a good chance to introduce the so much hated "S" curve via this combination of two turnouts. If you have the space to place a straight track of one cal length between all #4 turnouts you have possible also the space to use #6. But the optical impression of a parallel track with a distance of about 2' depends mainly on the angle of the turnout.
