[I'm goin' down]

I used your manual targeting tutorial, but usually had major problems with the range, and the direction of the target was usually inaccurate. But the concept of aspect ratio is quite interesting. Before I delve into your new tutorial, I want to point that the ship centered accuracy fix (SCAF) mod makes finding the range, aspect ratio and angle of bow a simple matter. Instead of determining range by matching up to the target's mast, you match up to another part of the ship (e.g., the smoke stack), so it is not as difficult as the task of matching up to the top of the target's mast, which is difficult to pinpoint at a distance. And you do not necessarily have determine the aspect ratio for accuracy.

I used it for the first time today, and the white "x" and white line showing the target's course on the Attack Map were on target. I mean exactly on target. (Maybe I got lucky). As the target moved into firing range the white x fell astern stlightly, which I attribute to a possible miscalcualtion of the target's speed. I fired and missed four shots to slightly to the stern of the target, but the markings on the attack map were where they were supposed to be. My ship only permitted slow torpedoe speed, and I do not know if that played a role in missing the shots. When calculating range on the stadimeter the trick appears to be matching the bottom of the waterline beneath the bottom of the top ("movable") target to the designated spot (i.e. the smoke stack) of the actual target.

If I strike out when I try it in the next few days, I will post a retraction. By the way, I delivered four torpedoes into a carrier yesterday, and although it made a major turn to port, it did not go down.
