Range doesn't matter when shooting with zero gyro angle if you precisely calculate target speed and torpedo speed.

You STILL don't get it. You also need that completely unspecified perfect 90 degree angle to the target track. Trigonometry ONLY WORKS for a right triangle. Leave that crucial piece of information out and precise target speed and torpedo speed alone won't hit the broad side of Hawaii! Buy a vowell and have Corey Harwell explain the situation to you.
Your inability to understand perfectly illustrates why I pick graphical solutions every time over numerical solutions. Inappropriate use of trigonometry, inappropriate use of apparent precision in carrying out calculations to four decimal places, and the inherent lack of error checking in numerical calculations and charts are just unnecessary. Calculations all have unstated preconditions for their validity. Those are not obvious when you are just working the numbers.
Graphical solutions are self-correcting. Put a starboard AoB in there instead of port and it's immediately obvious that you've made a mistake. That's why the attack map is a crucial step in setting up an attack. Just work the numbers and the error is undetected until the torpedo goes somewhere completely different than where you intended. Even if your calculations and table lookups are correct you can't tell when they are inappropriately applied.
Now defend your position that all you need is target speed and torpedo speed to make a valid solution (I've already snuffed that one), fix your method so it works, or go away.
