It's a mystery, that's for sure. But yes, as you change settings on the TDC and watch the attack map you can see the "bug" move smoothly, not in increments. And I can't think of a reason that would happen and then the TDC actually compute using whole numbers. Not only that, but suppose it did use whole numbers. That means every single calculation and intermediary calculation would be rounded. Every time you round you lose precision and with several stacked unpredictable things would occur.

Watching on the attack map I've never seen any effects of that. The torpedo always passes right through the "X." I suppose that calculations could be full precision and just the result rounded but even that would show.

Guess I'm going to spend some time on my Shooting Gallery Test Range with an uncharacteristically stopped submarine and a lot of test shots.

I've never heard the sonar operator call a fraction of a degree though. Now in real life the width of the zone of detection was of variable width, the peak in the center often not in the center and different factors like reflection off objects and underwater temperature gradients would change the bearing slightly even while you were trying to refine it. That made sonar bearings less accurate than visual or radar bearings. A sonar bearing within plus or minus one degree was exceptional and rare. With our sonars we can find the outside threshold on both sides and hit the center--that's the precise bearing. Real subs? Not so much.

Also there's a persistent problem with the bearing circles on the nav map where the scale is offset a degree and a half or so from our sub's track, I think to the right. I noticed, Colonel, that you commented on that during the video and how frustrating it is. You corrected to put zero on the bearing circle on your course. I always use the set course function and let the gauge show what it shows. Doesn't seem to matter much what you do.

I think Captain Scurvy worked on the orientation of the bearing circles and may have fixed them.

But first, greyrider, have you watched ColonelSandersLite's video on ? Watch it and learn. No, don't worry about the attack procedure. Pay attention to how to teach and what the goal of teaching is. Teaching a procedure magnitudes more complicated than your pretended "technique" he clearly instructs at a level that any intermediate or advanced SH4 player can put to work and use with great success. That is the model of instruction as opposed to empty boasting and inappropriate appeals to irrelevant historical authority. Sun Tsu couldn't work a TDC to save his life.
