Off_Topic, you've pointed folks to the original discussion thread which I suppose it good to make it easy for people to find the original discussions, but some of this information is long out of date. http://www.ja-galaxy-forum.com/board/ubbthreads.php?ubb=showflat&Number=262052#Post262052
is the thread (especially the last 4-6 pages of the thread) where alot of discussion and changes have been discussed. For instance, in the recoil presentation thread, Headrock mentions that 14 tiles is twice the normal shooting distance and therefore doubles the deviation factor for recoil. But this is no longer accurate since a seperate recoil distance (NORMAL_RECOIL_DISTANCE) was added specifically to deal with recoil accuracy.
Also, in his recoil presentation he states that "a generic assault rifle with a relatively powerful recoil....of +2,+5". A +7 recoil may have originally been what he considered "relatively powerful recoil" when he first wrote that presentation, but just look through the current weapons.xml at assault rifles with +2,+14 (FN FAL OSW) and you can see that a +7 really isn't all that "powerful" any longer.
Not that what you've done here is a bad thing. I just want people to realize that most of this information is from Headrock's original posts and alot of it has seen some pretty serious revision since it was released.
