Rat....
Obviously what I'm trying to explain to you is over your head. Guess I'm trying to explain rocket science to a guy who only knows how to light the wick on a bottle rocket.
I'll keep doing the calcs when I need to, like I've done for many years, because somehow they seem to be on the money when a manual check is done with the cam installed, and you can do whatever it is that you do, or is that can't do?
Maybe you could call someone like Bullet Cams and they might take the time to spoon feed you through it, because they too use these calculations..
Now...go away..
