Found these, as they go well with the Accuracy Reports and the Davis book, thought I'd stick them up in their own thread.
USAAF Intelligence Analysis Division reports. There's a good deal of speculation re: overall damage in Part I, but there's some good info on overall tons dropped per target system. There are also quite detailed and interesting reports of damage to individual target sites by USAAF raids in Part II- given the level of detail, I believe much of this must have come from post-raid bomb damage-assessment photo analysis.
