I would expect that rotating the drum any number of turns agrees with the arc engravings to the nearest degree winding it across the whole arc forwards and back, but is that really true?"
At your suggestion, I just tried that with my Mark 15. Starting at 0d, 35 positive rotations of the micrometer got me to 35d exactly, with precise alignment at each degree. I reset the index to 70d; 35 negative rotations got me to 35d with the same precision.
