In the example above, the 430d xDrive, 435d xDrive, 435i xDrive and 440i xDrive share the same set.
420i xDrive , 428i xDrive, 430i xDrive, 435i, 440i, 420d xDrive and 430d have a different set.
And even so.... the result is suboptimal for some....

You are saying there are 'just' two spring rate/spec options for the model range... Hence the wide fitting tolerances users are seeing. Axle weights will be very different, even for the models listed for a specific spring set.
The other factor as you have mentioned, is actual measurements. Requires a flat surface, more a workshop floor, than roads or parking areas.
