This is the result of a detailed study of the performance of the OOTP injury algorithm (discussed in a different thread some time back). It attempts to answer the question of whether the injury ratings make a difference, and, if so, define how big of an impact these ratings carry. The study is made with OOTP 5 data. I believe the injury algorithm has been left intact in v6 and beyond, but treat the study with kid gloves in that sense.
If you're a "Fog of War" kind of guy, and don't want an insight into how the game works, then this report may not be for you.
Of course, maybe I'm all wrong ... feel free to ignore as you wanna.
Since the document is too big to meet the site's 100K limit, I've put it on another site...I'll leave it here for awhile.
