As a quick side comment, the process of focussing with tilted lenses on a view camera is a lot simpler with cameras - like the Ebony - that have a so called assymetric tilt capability.
The assymetric tilt is based on the rotation axis of the film plane being located lower than the middle of the film.
Thanks to this there is no need to iterate in order to set the focus.
Just focus the location of the tilt axis at infinity and then tilt the film plane until the foregounrd comes into focus... voila...
There is a need to iterate several times with most cameras like the Linhof to get the same result and even if pre-computed angles help they just don't cut it when critical sharpness is required.
