Have you tried it?

Using your numbers with 3580 ticks around the circle:

If you're moving from 0 to 11 distance is +11.
If you're moving from 11 to 0 distance is -11.
In both cases the ABSolute value of distance is 11. If you have deadband set to 1 then you'll move because distance is larger than deadband.

If you're moving from 11 to 12 distance is +1.
If you're moving from 12 to 11 distance is -1.
In both cases the ABSolute value of distance is 1. If you have deadband set to 1 then you won't move because distance is not larger than deadband.
