had another thought : what if logistical strike damage, if not all air damage against ground targets, was logarithmic? So it would take more and more effort to cause damage against infrastructure as it approached zero. This would simulate destroying a few major bridges, for example, which are big targets and have a large impact on the transport network in a province, but requiring much more effort to destroy every road, trail, or railway yard. (not that destroying bridges was ever easy for pre air to ground missile air forces)
Also, If a province is given priority for rebuilding by clicking on that little green star, should the repair rate be equal to the destruction rate, or at least close? Like in that movie, Apocalypse Now, where the NVA bomb the bridge every day and the Americans rebuild it every night? (or was it the other way around?).
I don't know if the AI expresses priority for rebuilding provinces though. This could be taken from the provinces already mentioned in the AI files for IC or infra building, or for provinces which should be garrisoned.
