Sorry for bumping this old thread, but does that mean if you have a rather large nation in a PU under you (let's say France under a PU as England) that you can never inherit them? Because IC is determined negatively by # provinces from Junior. So as soon as IC drops below 0 due to high number of provinces, you can never inherit. And thus you are forced to integrate them with diplo points.
Or am I missing something?
