That's similar to my target, although mine is simpler, and I shoot from a greater distance -- five to ten feet, depending on the focal length. My target is 13 x 19, with lines about 3/8 inch apart. I've found that when tests are conducted carefully -- off a tripod -- and results are analyzed on the computer screen at high magnification, the test results repeatable. To me, that verifies their accuracy.
