Another way for manual TDC 100% realistic

Ok mates, I´m gonna be as especific as my non native english allows it. I´ve been practicing manual tdc for the last couple of days with Hitman Aob calculation, which is very good. sadly Im not fond about pausing the game to make some math, that was not possible for subs oficers so I tried this method which involves using the map and the tools. so please bear with me, here goes some pics so you can get an accurate idea what Im talking about.

Here comes Kongo, having a good time.... until now.
First steps:
- once you get to a good firing position, stop the sub.
- open you recognition manual, identify and send to TDC.
- note the bearing, measure the distance with the stadimeter and go to the map

- draw a circle equal to the target distance with the sub dead on center
- trace an angle equal to the target bearing (this case would be 61°)
- mark with an X the exact point they meet, here is your target.

- now to get the real bearing of the target we need another mark to draw a line, so lets change the angle to 55° and leave it there, we will come back later.

-ok, the idea is to wait and let the target come closer to those 55° in our map. In the meantime, take a minute to calculate the target speed with your method of choice. I used the lenght / time * 2 to get a very accurate reading. Send it to the TDC.

- as you can see, Kongo has reached those 55°, now take a quick distance measure, send it to the tdc and go to the map.

- now take the compass circle and redraw it to the new target distance. now you can make a straight line between those 2 marks, which will give you the real target bearing AND the AoB.

here is a fairly accurate AoB, put it in the TDC and go back to the scope.

ok, now you are ready to show Kongo who is the boss here .
You can start firing away, or wait a little for a better angle. Remember that the more you wait, the worst the solution will be.
Send the first 1 with no spread, and the others adding about 1° to each one (in this case all to the left according to the target bearing) to correct minor miscalculations.

Here they go in a nice spread.

Torpedo impact! and 2nd! and 3th!

and 4th too!!

All about 2k mts away.

All this takes a little more time to get it done (not much) but is fun to do. The distance between the first and the second mark on the map will give you a better solution if they are more distanced. It all depends on how much time you have to get the solution before the target slips away, of course. Sometimes would be useful, sometimes not.
