Ah-ha! This was revealing and disclosed the missing link. Turns out that as expected, the problem was me doing something stupid. In this case, code in a totally different source file was taking these values, much farther down the line, and re-scaling them again. I'd forgotten this old code existed, so it wasn't adapted to the new Cocoa order of things, and was doing it wrong.
Thanks everyone for letting me bounce this stuff off you (and for a lot of good insights into debugging this kind of code).
