See the PDFS for to-scale printouts of the paper jigs, and the images below for the numerical measurements.
Measurements are not rounded but presumably rounding to the nearest mm would be good enough.

Rottefella 75mm, NNN-BC and XPlore mounting hole metrics
I digitally measured the distances between mounting holes on the above Rottefella bindings.

Re: Rottefella 75mm, NNN-BC and XPlore mounting hole metrics
Summary:
- Maximum Screw mounting width of Xplore, NNN-BC and Rottefella Super Telemark are the same (2.6 cm between hole centers). Rottefella Cobra is wider.
- When remounting from NNN-BC to XPlore, you can re-use the same front two holes and your pin line gets moved backwards by 0.5 cm (or forwards by 2 cm, if you use the NNN-BC front holes as the XPlore rear holes)
- When remounting from Super Telemark to Xplore, if you re-use the ST toepiece rear holes, your pin line gets moved backwards by 2.4 cm (or by 5.4 cm if you use the ST rear ski holes on the XPlore front binding holes).
NNN-BC to XPlore: I suppose that 0.5 cm is probably negligible.
75mm to XPlore: What are the effects of moving the pin line backwards by 2.4 cm?

This is superb! Thank you so much for posting.
The data on reusing holes when switching binding types was particularly interesting.

We dreamed of riding waves of air, water, snow, and energy for centuries. When the conditions were right, the things we needed to achieve this came into being. Every idea man has ever had up to that point about time and space were changed. And it keeps on changing whenever we dream. Bio mechanical jazz, man.
