So on that basis seating 2 thou deeper will compensate for the 2 thou of headspace and maintain a 10 thou jump - yes?

By my math, you had 5 thou jump last time because the headspace took up 5 thou jump of the 10 thou you got from your BTO measurement. So you'd want to seat 3 thou further out now because the case will be taking up 3 thou less.

Or... Don't. Just leave the die alone, go shoot another group with your resized brass and see if you can notice any difference at all before making any changes.
