I think I saw the same Discovery episode. Those Trebs were dead on. I mean a couple of feet one way or the other is incredible considering the tech they were using. It seemed funny that most of the errors were because it was a very theoritical practice ... for them. Back in the day, a seige engineer, operator or the like would have an understanding of them that the Discovery Channel people just didn't.

Anyways, I never really gave it much thought until recently. I typically just starve the garrison out, but I have been playing the Cathos alot. When attacking another Catho, assaulting a Castle is typically a foregone conclusion because of the Pope. Well, I started playing the seiges, and was mortified at how inaccurate the mechanical seige engines were. The catapults were the only decent ones. So thats when I started poking around.

Hopefully Beriut will share the changes he makes with the rest of us. I'd be interested to know what he tweaked the cannons to and why.
