That's a good point about 7" records. They're a bit off my radar.
Funny thing is, that I've not seen anyone develop math around smaller formats. Stevenson would likely be the closest to an ideal alignment.
Frankly, I don't find distortion increasing across the record with Baerwald, so if I started collecting 45's, I'd likely stick with it - only because I'm not going to get out the protractor for every record ;-)
Cheers,
