You are right, I haven't neither the knowledge nor the practise to discusse about what you try to do or what you have alredy done
But more than problably it is an outstanding resource that might have great acceptance by the community
Of course, as long as you are able to convince me that this is even something to be considered a resource for this board, mostly because in my tests it failed always except when you are stopped: I got shot when putting back the weapon after killing some soldiers, or when using binocs (stopped too), I'm free to take out the gun all the time walking backwards, or just walking, I'm also able to take out the gun pressin Z twice to get crouched. Based on your theory about "sizes", if player lay down it occupies more space trigger-wise, right? Something fails, because I'm free to lay down with the weapon in hand.
