I'm surprised these haven't already been mentioned:

For swings and tilts you use the same method with one caveat.

I can not get my head around this: when you position the plain of sharp focus with a tilt
and use a near and far point to do so then these two points are in focus when the tilt is correct,
so there is no difference in distance on the camera for these two points.

With a "zero" camera setup I totally understand the technique of near and far points because
there "is" always a distance on the camera between those two points, then devide by two
to set camera and multiply by 5 for aperture setting (5 in case of a 4x5 camera).
But with a tilt the near and the far point are both in focus for the same distance on the camera
when the tilt is correctly setup for the plane of sharp focus one has in mind.

Could you please explain some more this method when using tilts ?

Thank you !
