There are occasionally times when I'm thankful I was awake in a couple of my math classes.
Last night I asked, "is my rear sight centered?"
No. It was not. From the side of the frame to the base of the rear sight on the left side of the gun it measured 0.109" and from the right side it measured 0.083".
I could have moved the sight to the left and measured both sides until they matched, but I can haz maths!
The distance to center is one half the difference of the measurements.
(0.109" - 0.083") / 2 = 0.013"
The sight mover uses a 3/8-16 UNC thread pusher. So every complete rotation of the screw is 1/16" of an inch or 0.0625".
0.0625 / 0.013 is 0.208 which means about 1/5 of a turn to move the sight where I needed it.
And you thought I wasn't listening, didn't you Mr Smalling?
