I process bulk for people as well, and would not own the machine without the sensor. I did originally and had tons of issues.
If I get a batch that has been deprimmed, I turn the sensor off.
Between the decap senor and the swage sensor, I know that every piece of brass is decapped and swagged properly, and do not have the issue of a ringer advancing to the next station or causing jams, dented brass, or indexing problems.
