I just recently got into bowhunting and I have a Trophy Ridge Flatliner 3-pin sight. A 10 yard, 20 yard and a 30 yard pin.

I got my 10 yard sighted in no problem, I made some adjustments to get my tight groups that im looking for. Now when im trying to sight in my 20 yard pin and I will have to adjust the sight most likely. Will that directly effect my ten yard pin and set it off? It seems like it would when im moving the sight up and down and left and right. Is there a way around this or am I just talking crazy?
