Knowing how to read is not the same as having comprehension. Rote copying of material you do not understand does not bolster your case.
From time to time people pop into Subsim with crazy ideas that they are the only people in the history of mankind to come up with a completely new method of shooting torpedoes. They make grandiose statements and outlandish claims, then make themselves appear sane by quoting the 1946 Submarine Torpedo Fire Control Manual.
Of course it does NOT support your method. Your method is invalid and cannot be used to accurately aim a torpedo. Those guys seventy odd years ago were way ahead of you.
And you don't understand either the vector analysis method or the Dick O'Kane method. I use the accurate analog trig computer built into the TDC to eliminate inevitable human error and PRECISELY pick the gyro angle, which the selection of lead angle by rule of thumb, not guessing, ensures will be well under 10 degrees. Any gyro angle of under 20 degrees is considered straight shooting where range error is not going to result in missing the target. There's nothing magic about fussing with getting a perfect zero gyro angle shot. Read the freakin' manual you so love to quote! A little understanding would lead you to sheepishly withdraw all you've said. Any fool can retype irrelevant passages. You sure have.
Now either support your foundation statement, "the only two pieces of information you need to shoot a torpedo are target speed and torpedo speed." or go away.
There was another equally deluded guy who claimed that putting the enemy on your 80 degree or 280 degree bearing guaranteed his course was at right angles to your own.... He loved to quote the Submarine Torpedo Fire Control Manual in invalid ways too. Hint: the STFC manual does not depend on Black Magic.

Trigonometry is not black magic.
Here you go.
27 knot Yamato
46 knot torpedoes
From my table 30 degree firing bearing.
I never touch the TDC or develop a range, AOB or any of that other unnecessary stuff.
As long as you are in a firing position with the head of the boat 70 to 110 degrees off the target bearing, the table of values works like a charm.
