The contrary positions to the .001 to .002 variations that are eliminated by adequate dwell time are:
1. You are claiming that slam bang operation of your reloading press will produce more consistent shoulder position than will slow deliberate operation of the press.
2. You are claiming that the meticulous maintenance of the shoulder position by FL sizing and by shoulder bumping produces worse accuracy than inconsistent technique when resizing your brass.
I think If you examine the contrary positions you will find they are very good arguments for carefully controlled press technique.
