Actually 2.866 degrees off spindle axis will get you half a tenth infeed, needed for one tenth on dia.
This assumes compound is one to one, unlike the normal two to one crossfeed dial.

5.73 degrees will give you a 10:1 reduction.
Stand in front of a lathe for ten years and you can turn a tenth, doesn't matter what the compound angle is. Not before.
Truthfully, the monarchs divisions are wide enough, that with care, IE, same approach cuts every time, you can come within a couple thou on your rough, and tap it in to a few tenths every time. Beats screwing up your Z dimension to try with the compound
