I’m trying out the OnTarget Precision Calculator program; I wished I’d found it a year ago. Now I can do in a couple of minutes (and to 0.001 of an inch) what used to take me 10-15 minutes to try to do with a photo editing program.
After I set the scale and mark the shots, the program determines the center of the group and then draws the rectangle through the center-line of the two or three most outlying shots, and the circle from the center point using the mean radius. The mean radius (as defined in Hatcher's Notebook) “is the average distance of all the shots from the center of the group.”
I call the one set of targets "Red Dawn" because the soldier's helmet looks Soviet bloc to me. They are life-size targets. And, I call the other the Nazi Vampire because, well, he looks like a stormtrooper who's one of the undead. He's not quite life-size.
