Correct; chains don't wear in a uniform fashion. Rotate the wheel until the tightest point in the chain is about halfway between the sprockets, and take your before and after slack measurements from there. Also, just before you tighten the axle nut, place an Allen wrench (doesn't have to be an Allen wrench but that's what most folks use; 6mm often does the trick) between the sprocket and the upper run of the chain, and then rotate the wheel backward to lock it in place against the adjusters, and hold while tightening the axle nut. This will prevent the wheel from moving slightly when the axle nut is being torqued down and throwing off your slack and/or alignment.
