Need to know the radius and length of a curved track to use with #5 and #6 so that I can run the "turned out" leg parallel to the main leg from which a train has exited.  Eg: do I use a 22" radius 9" long curve section to "bend" the track exiting from a main line with a #5 switch, back so it's parallel?

We know that a 9" long 18" radius track will bring a standard (unnumbered) switch turned leg parallel to the main line -- but how about for #5 and #6 switches?
