I think this is spot on - I think the loop with the two points adding an
outer half-circle illustrates it best.
What you want to be able to do is to take a quarter circle with a straight
added to each end, and have your new curvature fit that.
Anything else is just asking to complicate the geometry even further. 16
studs between centres should be enough passing room (Nazi gun trains
notwithstanding :-).
