This makes sense: so when I'm at '0 degs' my A phase is on 100%, B phase is zero. Or, the way I've my LUT written, I'll have A at 0 and B at full-width positive. If I don't like this for some reason (It'll calibrate away) I can change the LUT.
FWIW **at 2021 02 03** I ended up drawing this out later:

In the stepper, we have one 'complete electrical phase' inside of four of what we normally call 'steps' - this spans 7.2 physical degrees when we have a 200 'step' (pole) motor.
I'm up to pointing, now I just need to deliver some power to the motor.
OK, this is making sense and I can point my magnetic vector around:
