An explanation is needed for the AOF finder re Aob

I do not play SH3. I play ATO (SH4.) I am posting here because not many captains post in the ATO forum.

I am famailiar with the AOBF, and use it always. I have read the tutorial by kazarmozovnew, and am familiar with it. In the tutorial example, he determines the Aob of a German Battleship. Because the periscope is set to 6x zoom, the Aob for the Battleship, per the example, is 52 degrees (i.e. your multiply the reticules for the battleship's length (13) by 4.) The AOBF calibrates to 50 degrees which is astride the verticle line on the top of the wheel, and he determines the 52 degrees mark on the 'wheel' via logarithims (his tutorial says that the scale is "logarithmic.") He provides no other explanation or examples. I do not understand the concept and how it fits into the using the wheel.

I just had an encounter with a target moving away from my boat, where the wheel readings where far in excess of the reading on the vertical line on wheel, and frankly, I lacked the expertise to calculate the Aob. Is there an explanation somewhere? I am not sure where to look. Someone who is familiar with the wheel and with karamozovnew's tutorial would be the person who might be able to give me a thorough response. I could not copy the relevant pages of his tutorial, which are unnumbered, as it is in Adobe format.
