I'm not sure how to even do the alternative.

Screen shots of O-scope traces of the two signals showing a full rev. would be great.

I am an idiot some times. For Hall effect sensors, one pole, one edge*

12 edges would need 12 poles (N-S-N-S-N-S-N-S-N-S-N-S).

*unless it was one off those "reed switch replacement" Halls that go on based on the field strength being above a threshold in either the N or the S direction, this would be a terrible choice for this application so I think we can all agree that me being an idiot at times is the best answer and move on.
