AOB Bug or am i just plain stupid??

Well lets see the AOB has been something that has plagued the subsim community since the very first silent hunter series came out. I learned it pretty good in SH3 and would use my much missed weapon officer to confirm it until i got good. In sh4 they decided that i had to earn my pay and fired him i guess.

The problem is that if im correct AOB can simply be explained as
The angle at which the targeted ship would report seeing the submarine. (please correct me if im wrong here) But basically it is opposite of what everyone thinks.

The way im hunting now i approach the target very quitely and slowly, most of the time trying for a 90 degree attack. A take several range reading using the little button the brings up the range finder, i click that then calculate or guess the speed using several methods. (I also tried this on a mission i made up using 8kts as a fixed speed to make sure it is not a speed error) I put in my 8kts using the little tool with the kts marking on it. I click the send button. Then comes the AOB. I can never seem to get this right even if I'm set up for a 90 degree shot or as close to it as possible.

The way im doing it is by drawing a line using the ruler that is the target ships course heading, usually taken from several marked positions "X's" This line in the target ships course. I then take the protractor tool and place on end or first point at the end of the targeted course, The second mark i place at the bow or slightly inside the fore area of the targeted ship, the third and final point i place on the bow of my submarine zooming in on the nav map. This will give me an angle and then i simply plug it into the AOB tool. (I tell port and starboard based on the side the targeted ship is showing me) I send this to the TDC and then click on the buttons that allow the information to be updated provided the ship stays on course.

However even with what i feel is a correct solution the torps are passing WAY ahead of the target or doing things i never expected them to do. Without the weapon officer i cant check the AOB and firing solution, so im looking for help. I have to be doing something wrong here and im not sure what it is. When i look at The AOB dial it appears that the ship is opposite of what it looks like out the scope and on the nav map.

The other problem comes in when I try and shoot from the aft tubes, i cant get a torp to fire correctly from there either, is the AOB from the aft tube calculated usinf the aft part of the sub or the bow. I couldn't see it being the bow so i tried the aft section, still no joy.

Could someone please also explain the how the spread angles work, when it say left and right is that refering to a target moving left to right or vic a versa?

I know many people ask about the AOB but im still not getting it in SH4, could someone explain a method similar to the one im trying on the map. Also be nice to see it done from odd directions and a stern shot.

Thanks
sorry for my stupidity, lol
Time to return to the Atlantic (They are going to fire me anyway)

Has anyone figured out a workaround for using the FAST setting on the torps as i know one bug is the speed settings, however all my shots were done using the slow settings and "contact"?
