Correct, I am talking about shots that land off screen. They do NO damage. I checked this out, by looking at the population of a planet that had previously had it's facilities destroyed. There were no WP in place, the only targets were population. Upon firing 4 depleted uranium cannon IVs at 99% accuracy and half the planet not in the view, no reduction in population was done. upon firing the next volly from another duplicate ship but with the full planet in view, damage was calculated correctly.
This paticular planet was "small" but as you know the planet uses a certain size box. Say your attacking from the south side. If the north row of the planet box is not in the view, the volley will fail. Even tho it "looks" like the planet is in view.
