That explains a lot, MarkerInbound, thanks for the reference!
Surprisingly intricate (not to say dirty) business, this VOR / Victor airway navigation! But as you say, MarkerInbound, probably not too much of an issue for practical purposes. However, not all VOR navigation is done via Victor airways but arbitrary tracks to / from a VOR. Thus it would be good to outline the correct procedure to obtain the correct magnetic heading for VOR navigation.
So I guess the the appropriate method to obtain a magnetic heading from a Victor airway is to take its stated magnetic heading on the sectional [1]. In the case of an arbitrary course to / from the VOR, the most appropriate magnetic track seems to come from the intersection of the track line with the VOR rose (which is a somewhat inaccurate measurement due to the small geometric scale on the chart), as opposed to to measuring the true track with a protractor and apply variation to magnetic.
BTW, there's an interesting side effect to the misalignment of VORs: One airway connecting two unaligned VORs would have two magnetic headings (i.e., one for each direction) that are not exactly reciprocal as a consequence.
