SvS hitting damaged areas

[Glib]

Since the new SvS puts a big premium on hitting areas of the ship that are already damaged (a 10-fold increase in cannon damage if you hit an already damaged area!!) Has anyone noticed that it's not exactly clear where these damaged areas are?

I've hit right on a burning section of hull and get the low level points, then hit just off to one side and get the high level points. Plus some shots that miss the hull and hit the deck or cabin seem to score big. The weak areas seem to be randomly "around" where you see signs of damage (fires, holes etc.) but not right on them. Makes it kind of hard to hit them.

Also anyone have any idea how long you have to bang away before you create a damaged area. With the 10x reduction in cannon damage on virgin hull the difference between my iron shot and my thunderbolts isn't really that great (22pt vs 81pts. = 59 pts difference)

Maybe I should try and damage the hull with iron shot and only use T-bolts on already damaged areas. You can go through a lot of T-bolts in SvS!
