Range is from the aircraft to the middle of the crosshairs. Given the Spectre flies in circles around the X, if the crosshairs aren't directly on a target, somewhere during the circle the Spectre will be closer to the target.

What you want to do when trying to stay away from a target is put the far edge of the box just touching the target. However, since that means the centre isn't on the target, you'll need to retarget before your arc brings you too much closer to the target.
